Development Tools  
PSoC Designer™ is a Microsoft® Windows-based, integrated  
development environment for the enCoRe and PSoC devices.  
The PSoC Designer IDE and application runs on Windows XP  
and Windows Vista.  
Assemblers. The assemblers allow assembly code to be  
merged seamlessly with C code. Link libraries automatically use  
absolute addressing or are compiled in relative mode, and linked  
with other software modules to get absolute addressing.  
This system provides design database management by project,  
an integrated debugger with In-Circuit Emulator, in-system  
programming support, and built-in support for third-party assem-  
blers and C compilers.  
C Language Compilers. C language compilers are available  
that support the enCoRe and PSoC families of devices. The  
products enable you to create complete C programs for the  
PSoC family devices.  
PSoC Designer also supports C language compilers developed  
specifically for the devices in the enCoRe and PSoC families.  
The optimizing C compilers provide all the features of C tailored  
to the PSoC architecture. They come complete with embedded  
libraries providing port and bus operations, standard keypad and  
display support, and extended math functionality.  
PSoC Designer Software Subsystems  
Chip-Level View  
Debugger  
The chip-level view is a traditional integrated development  
environment (IDE) based on PSoC Designer 4.4. You choose a  
base device to work with and then select different onboard  
analog and digital components called user modules that use the  
PSoC blocks. Examples of user modules are ADCs, DACs,  
Amplifiers, and Filters. You configure the user modules for your  
chosen application and connect them to each other and to the  
proper pins. Then you generate your project. This prepopulates  
your project with APIs and libraries that you can use to program  
your application.  
PSoC Designer has a debug environment that provides  
hardware in-circuit emulation, allowing you to test the program in  
a physical system while providing an internal view of the PSoC  
device. Debugger commands allow the designer to read and  
program flash, read and write data memory, read and write I/O  
registers, read and write CPU registers, set and clear break-  
points, and provide program run, halt, and step control. The  
debugger also allows the designer to create a trace buffer of  
registers and memory locations of interest.  
Online Help System  
The tool also supports easy development of multiple configura-  
tions and dynamic reconfiguration. Dynamic reconfiguration  
allows for changing configurations at run time.  
The online help system displays online, context-sensitive help  
for the user. Designed for procedural help and quick reference,  
each functional subsystem has its own context-sensitive help.  
This system also provides tutorials and links to FAQs and an  
Online Support Forum to aid the designer in getting started.  
System-Level View  
The system-level view is a drag-and-drop visual embedded  
system design environment based on PSoC Designer.  
In-Circuit Emulator  
Hybrid Designs  
A low cost, high functionality ICE (In-Circuit Emulator) is  
available for development support. This hardware has the  
capability to program single devices.  
You can begin in the system-level view, allow it to choose and  
configure your user modules, routing, and generate code, then  
switch to the chip-level view to gain complete control over  
on-chip resources. All views of the project share common code  
editor, builder, and common debug, emulation, and programming  
tools.  
The emulator consists of a base unit that connects to the PC by  
way of a USB port. The base unit is universal and operates with  
all enCoRe and PSoC devices. Emulation pods for each device  
family are available separately. The emulation pod takes the  
place of the PSoC device in the target board and performs full  
speed (24 MHz) operation.  
Code Generation Tools  
PSoC Designer supports multiple third-party C compilers and  
assemblers. The code generation tools work seamlessly within  
the PSoC Designer interface and have been tested with a full  
range of debugging tools. The choice is yours.

Designing with PSoC Designer  
The development process for the enCoRe V device differs from  
that of a traditional fixed function microprocessor. Powerful  
PSoC Designer tools get the core of your design up and running  
in minutes instead of hours.  
Generate, Verify, and Debug  
When you are ready to test the hardware configuration or move  
on to developing code for the project, you perform the “Generate  
Configuration Files” step. This causes PSoC Designer to  
generate source code that automatically configures the device to  
your specification and provides the software for the system.  
The development process can be summarized in the following  
four steps:  
1. Select Components  
Both system-level and chip-level designs generate software  
based on your design. The chip-level design provides application  
programming interfaces (APIs) with high level functions to  
control and respond to hardware events at run time and interrupt  
service routines that you can adapt as needed. The system-level  
design also generates a C main() program that completely  
controls the chosen application and contains placeholders for  
custom code at strategic positions allowing you to further refine  
the software without disrupting the generated code.  
2. Configure Components  
3. Organize and Connect  
4. Generate, Verify, and Debug  
Select Components  
The chip-level view provides a library of pre-built, pre-tested  
hardware peripheral components. These components are called  
“user modules.” User modules make selecting and implementing  
peripheral devices simple, and come in analog, digital, and  
mixed-signal varieties.  
A complete code development environment allows you to  
develop and customize your applications in C, assembly  
language, or both.  
The last step in the development process takes place inside  
PSoC Designer’s Debugger (access by clicking the Connect  
icon). PSoC Designer downloads the HEX image to the In-Circuit  
Emulator (ICE) where it runs at full speed. PSoC Designer  
debugging capabilities rival those of systems costing many times  
more. In addition to traditional single-step, run-to-breakpoint and  
watch-variable features, the debug interface provides a large  
trace buffer and allows you to define complex breakpoint events  
that include monitoring address and data bus values, memory  
locations and external signals.  
Configure Components  
Each of the components you select establishes the basic register  
settings that implement the selected function. They also provide  
parameters and properties that allow you to tailor their precise  
configuration to your particular application.  
The chip-level user modules are documented in data sheets that  
are viewed directly in PSoC Designer. These data sheets explain  
the internal operation of the component and provide perfor-  
mance specifications. Each data sheet describes the use of each  
user module parameter and contains other information you may  
need to successfully implement your design.  
Organize and Connect  
You build signal chains at the chip level by interconnecting user  
modules to each other and the I/O pins, or connect system-level  
inputs, outputs, and communication interfaces to each other with  
valuator functions. In the chip-level view, you perform the  
selection, configuration, and routing so that you have complete  
control over the use of all on-chip resources.

Register Reference  
The section discusses the registers of the enCoRe V device. It lists all the registers in mapping tables, in address order.  
Register Conventions  
Register Mapping Tables  
The register conventions specific to this section are listed in the  
following table.  
The enCoRe V device has a total register address space of 512  
bytes. The register space is also referred to as IO space and is  
broken into two parts: Bank 0 (user space) and Bank 1 (configu-  
ration space). The XIO bit in the Flag register (CPU_F) deter-  
mines which bank the user is currently in. When the XIO bit is  
set, the user is said to be in the “extended” address space or the  
“configuration” registers.

3. Higher storage temperatures reduce data retention time. Recommended storage temperature is +25°C ± 25°C. Extended duration storage temperatures above 85 C  
degrade reliability.  
4. Human Body Model ESD.  
5. According to JESD78 standard.  
6. The temperature rise from ambient to junction is package specific. See Package Handling on page 25. The user must limit the power consumption to comply with this  
requirement.

Package Handling  
Some IC packages require baking before they are soldered onto a PCB to remove moisture that may have been absorbed after leaving  
the factory. A label on the package has details about the actual bake temperature and the minimum bake time to remove this moisture.  
The maximum bake time is the aggregate time that the parts exposed to the bake temperature. Exceeding this exposure may degrade  
device reliability.
