IMPORTANT
Notes on Differences between Actual MCU and Emulator:
• Emulator operation differs from emulation of a mask MCU, as listed below. For details refer to
"Chapter 5. Precautions to Be Taken When Debugging".
(1) Reset condition
(2) Initial values of internal resource data at power-on
(3) Internal ROM and RAM capacities, etc.
(4) Electrical characteristics
(5) Operation in the power-down mode
(6) Operation of the watchdog timer function
(7) Port I/O Timing
(8) Pullup transistor control
• Therefore, always be sure to evaluate your system with an evaluation MCU (onetime version).
Also, be sure to perform board-mounted evaluation with ES (Engineering Sample) version MCU
to make final confirmation of device operation before starting mask production.
Note on the Target System:
• Make sure that the target's supply voltage is + 3.0 V or + 5.0 V. Therefore the target's supply voltage
should be in the range of + 3.0 V ±10% or + 5.0 V ±10%.
Notes on Connecting the Target System:
• When connecting the emulator probe, be careful to the wrong connection.
• When connecting the emulator probe, be careful to the warp of the cable. The warp may cause
breaking the wire.

a. Connecting to the IC socket for 32-pin SDIP on the Target System
Connect the M34514T-MCU board with the IC socket for 32-pin SDIP on the target system
using the 50-wire normal-pitch cable (included) with the M34513T-PTCA pitch converter
board attached. Figure 4.10 depicts the connection between the M34513T-PTCA pitch con-
verter board and the target system. Following products are required for connection to the target
system.
• 100-wire half-pitch cable (40 cm)
• PCA4029 pitch converter board
• 50-wire normal-pitch cable (10 cm)
• M34513T-PTCA pitch converter board
Table 4.9 shows the connector signal assignments of the M34513T-PTCA pitch converter
board. The pin assignments of M34513T-PTCA is the same as for the 32SDIP in 4513 Group.
When connecting the M34513T-PTCA pitch converter board, make sure the No. 1 pin position
of each connector is aligned with that of cable. To avoid damage to the emulator and target
system, be careful of the connection.

b. When Connecting to a 32-pin LQFP Foot Pattern on the Target System
Attach the pitch converter boards M34513T-PTCA and M34513T-PTCB to the 50-pin normal-
pitch cable (included with this product). Then connect the cable via the M34513T-PTCC to the
TQPACK032SA that has been soldered to the 32-pin LQFP foot pattern on the target system.
Figure 4.11 shows an example of how to connect to the target system using the M34513T-PTCA,
M34513T-PTCB, and M34513T-PTCC. Following products are required for connection to the
target system:
• 100-wire half-pitch cable (40 cm)
• PCA4029 pitch converter board
• 50-wire normal-pitch cable (10 cm)
• M34513T-PTCA pitch converter board
• M34513T-PTCB pitch converter board
• M34513T-PTCC pitch converter board (TQPACK* included)
* TQPACK consists of TQSOCKET032AF, TQSOCKET032SAP and TQPACK032SA.
Table 4.10 shows the connector signal assignments of the TQPACK032SA. When the
TQPACK032SA and M34513T-PTCC are used for target system connection, the pin assign-
ments are the same as for the 32LQFP in 4513 Group.
Solder the TQPACK032SA to the 32-pin LQFP foot pattern on the target system. The No. 1 pin
of the TQPACK032SA is located at its corner-cut part of package. Attach the M34513T-PTCC
to the TQPACK032SA with its No. 1 pin position (marked by a white dot) aligned with that of
the TQPACK032SA. After attaching the pitch converter boards M34513T-PTCA and M34513T-
PTCB to the 50-pin normal-pitch cable, connect the cable to the M34513T-PTCC. To avoid
damage to the emulator and target system, be careful of the connection.
When connecting cable and attaching the pitch converter boards, make sure the No. 1 pin
position of each connector is aligned with that of cable. Figure 4.12 shows the external view of
the TQPACK032SA and M34513T-PTCC.

5. Precautions to Be Taken When Debugging
5.1 Reset
The M34514T-MCU uses a 74AC14 for its RESET signal input buffer, so that its electrical
characteristics differ from those of the actual chip. Table 5.1 lists the RESET signal input
characteristics of the M34514T-MCU.

5.2 System Clock
Depending on the supply voltage and operation mode, use one of the following frequencies for the
system clock:
• Supply voltage 5 V: 4.2 MHz or less (medium-speed/high-speed mode)
• Supply voltage 3 V: 4.2 MHz or less (medium-speed mode), 2.0 MHz or less (high-speed mode)
To change this clock frequency to suit that of the target system, attach the necessary parts to the
oscillator circuit board OSC-2 that are included with the M34514T-MCU package.
For details about the oscillation circuit constant, consult your oscillator manufacturer.
5.3 Real-time Capability of Timer
The PC4504 and M34514T-MCU have their internal clock operating even during emulation, so that
the timer values keep changing.
Example:
(1) When single-stepping the program
(2) When registers or internal RAM are referenced or modified

5.4 Watchdog Timer
The M34514T-MCU does not have an operational watchdog timer. Therefore, use an evaluation
MCU (OTP version) to verify the operation associated with a watchdog timer.
The M34514T-MCU outputs a signal whose waveform is shown below from the check pin TP5
during WRST instruction execution cycles. This signal allows you to check the initialization cycle
of a watchdog timer.

System clock
XIN

Figure 5.1 Waveform output from check pin TP5
5.5 Pullup Transistor Control
Since ports P0 and P1 contain emulation circuits, you can not control the pullup resistors using the
pullup control register PU0. If you want to use the internal pullup resistors, turn on switches SW4 to
SW7 to activate the pullup resistors on the M34514T-MCU board.
The port's resistance value of the pullup resistor (RA1) is 68 kΩ.

5.6 Port I/O Timing
(1) Port input timing
Port input timings are the same as with the actual MCUs.
(2) Port output timing
When using the M34514T-MCU, output timings are different from those of the actual MCUs for
the following ports that are configured with port emulation circuits:
• Ports P00 to P03
• Ports P10 to P13
• Ports D0 to D5
With the actual MCUs, changes occur at the beginning of the T3 state of an output instruction.
With the M34514T-MCU, changes occur at the beginning of the T2 state of the next output
instruction. Figure 5.2 shows the port output timings of the actual MCUs and M34514T-MCU.
For the other ports, the output timings are the same as with the actual MCUs.

5.7 Port I/O Characteristics
With the M34514T-MCU, port I/O characteristics are different from actual MCUs because there is
an emulation circuit in ports P0, P1, P2 and D0 to D5. Table 5.2 lists port I/O characteristics of the
M34514T-MCU.

5.8 Power-down Mode
In the power-down mode, the M34514T-MCU operates differently from the actual chip of each
MCU.
(1) Power-down operation of M34514T-MCU
Although the actual chip of each MCU is placed in the power-down mode by executing a
combination of EPOF and POF instructions, the M34514T-MCU is placed in the power-down
mode by only the POF instruction.
In the M34514T-MCU, the EPOF instruction does not have any effect.

5.9 Program Execution (G, GB)
The PC4504 and M34514T-MCU’s hardware are subject to the following restrictions with respect
to the operation of the program execution commands (G and GB).
(1) Continuous description of instructions
Hardware breakpoints set in a continuous description of instructions following one after another
do not cause a break to occur in the continuous description of instructions. A break occurs only
after fetching the address where the continuous description of instructions is discontinued. (See
Program example 5.3)
However, a break does occur even in a continuous description of instructions when an external
trigger break or forced break is encountered. For execution to be resumed in this case, you need
to make sure that the execution start address is next to the continuous description of instructions.
(See Program example 5.4)

(2) Skip instructions (e.g. SNZP, INY, DEY, SZB, SEAM, SZC and RTS)
When a skip instruction skips the next instruction, a breakpoint set in the skipped instruction does
not cause execution to halt. (See Program examples 5.5 and 5.6)
