RESET FUNCTION
When a low level is input to the RESET pin, the system is reset, and each hardware enters the initial status
(reset status). When the RESET pin goes high, the reset status is released, and program execution is started.
Initialize the contents of each register through program as necessary.
Especially, change the number of cycles of the programmable wait control register as necessary.
The RESET pin is equipped with a noise rejecter circuit of analog delay to prevent malfunctioning due to noise.
Caution While the RESET pin is active (low level), all the pins go into a high-impedance state (except

Figure 6-1. Accepting Reset Signal
To effect reset on when power is applied, make sure that sufficient time elapses to stabilize the oscillation
after the power is applied until the reset signal is accepted, as shown in Figure 6-2.
