Reset input
from the XTAL pin (pin 23), it takes up to 20 clocks (about 1.2 s) before the statuses of all the pins are defined. To
allow for this, therefore, be sure to input the reset signal for a sufficient amount of time.

Pin No.
100
Cautions 1. Do not allow any input pin to exceed the power supply voltage.
Remark The meanings of symbols in the I/O column are as follows.
In the PD63711, when the reset signal (active low) is input from the RST pin (pin 3) while the clock is being input
