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 Item H-level threshold voltage L-level threshold voltage Hysteresis voltage Symbol VP VN VH Voltage Minimum Maximum VCC = 3.0 V - 2.2 V VCC = 4.5 V - 3.2 V VCC = 5.5 V - 3.
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. WRST instruction Next WRST instruction System clock XIN WRST Figure 5.1 Waveform output from check pin TP5 5.
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.
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. Table 5.2 Emulation port I/O characteristics Port Device Item VIH Input 74HC4050 VIL P0, P1 Output 74LS06 Voltage Min. Max. VCC = 2.0 V 1.5 V - VCC = 4.5 V 3.15 V - VCC = 2.0 V - 0.5 V VCC = 4.5 V - 1.35 V IOH - 250 µA IOL - 40 mA - 0.
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. Program example 5.1 Actual MCU The power-down mode works.
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.
(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 POINTA: TAM 0 POINT: TABP 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.

Instruction Next Instruction System clock XIN External trigger signal TRIG Figure 5.3 Latch timing of external trigger signal (2) External trigger signal input characteristics Trigger breaks work according to the condition (leading edge/trailing edge) of signals input from the external trace cable.
