Note on Watchdog Timer:
Note on Port Electrical Characteristics:
Notes on Port I/O Timings:
With this product, the watchdog function cannot be used. However, the watchdog timer initialization cycle can
be verified by observing the waveform at the check pin (WRST) of the emulator. For details, refer to “2.10
Watchdog Timer Initialization Cycle Check Pin” (page 38).
With this product, DWDT instruction (stop of the watchdog timer function enabled) cannot be used.
Because the following ports are configured with port emulation circuits, electrical characteristics differ from
those of the actual MCU.
Port input timings
Port I/O timings
Figure 4.1 Port I/O timings
As a pitch converter board and other devices are used between the evaluation MCU and the user system. Some
characteristics are slightly different from those of the actual MCU. Therefore, be sure to evaluate your system
with an evaluation MCU.
- P00-P03
- P10-P13
- D0-D1, D4-D5
- RESET#
For more details, refer to “4.3 Connection Diagram” (page 60).
Port input timings are the same as with the actual MCUs.
Port I/O timings are different from those of the actual MCUs for the following ports that are configured with
port emulation circuits:
- P00-P03
- P10-P13
- D0-D1, D4-D5
With the actual MCUs, changes occur at the beginning of the T3 state of an output instruction. With this
product, changes occur at the beginning of the T2 state of the next output instruction. Figure 4.1 shows the port
I/O timing for this product.
The output timings of ports D2, D3 and ports P30, P31 are the same as with the actual MCUs.
