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.

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.
Table 5.1 RESET signal input characteristics
H-level threshold voltage
L-level threshold voltage
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
( 29 / 42 )
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
WRST
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
(2) Port output timing
Port input timings are the same as with the actual MCUs.
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)
Program example 5.3
POINT: LA 1 ; Continuous description of instructions
POINT+2: XAM 3
If a break is set at POINT, execution is halted immediately before the XAM instruction at
address POINT+2.
LA 0
LA 2
Program example 5.4
LA 0
POINT: LA 1 ; Continuous description of instructions
POINT+1: LA 2
POINT+2: XAM 3
If a forced or external trigger break is applied at POINT, execution is halted at POINT +1.
When resuming program execution after the break, make sure that the start address is at
POINT+2, an address immediately after the continuous description of instructions is
discontinued.
( 34 / 42 )
(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)
Program example 5.5
RC SC
SZC SZC
POINT: TABP POINT: TABP
POINTA: TAM 0 POINTA: TAM 0
• •
• •
A breakpoint set at address POINT causes execution to halt immediately before address
POINTA in only the case of the instruction shown on the right side.
Program example 5.6
RC ; Skip instructions
INY
POINT: TABP
LA 0
•
•
If a break with pass count is set at address POINT, the count is taken and execution is
halted only when the instruction at address POINT is executed.

Trigger breaks work according to the condition (leading edge/trailing edge) of signals input from
the external trace cable. The external trigger signals of the trace points and the external trigger
signals of the break points use the same signals. The input characteristics of the external trigger
signals are shown in Table 5.3 below. See the table before using external trigger signals.
