The
μ
PD750008 is reset with the external reset signal (RESET) or the reset signal received from the basic interval
timer/watchdog timer. When either reset signal is input, the internal reset signal is generated. Fig. 9-1 shows the
configuration of the reset circuit.
Fig. 9-1 Configuration of Reset Functions
When the RESET signal is generated, all hardware is initialized as indicated in Table 9-1. Fig. 9-2 shows the reset
operation timing.
