9. RESET FUNCTION
watchdog timer. When either one of the reset signals are input, an internal reset signal is generated. Figure 9-
1 shows the circuit diagram of the above two inputs.
Figure 9-2 shows the timing chart of the reset operation.
There are two reset inputs: external reset signal (RESET) and reset signal sent from the basic interval timer/
The PD753017 is set by the RESET signal generated and each device is initialized as listed in Table 9-1.
Note The following two times can be selected by the mask option.
