Provides voltage for FDP when on-chip resistor is selected under mask

option.

Connection for system clock oscillation crystal. When using an external

clock, input normal signal to EXTAL and reverse phase signal to the

XTAL pin.

System reset, active "L". The RST pin is an input/output pin which

outputs a "L" level from the on-chip power-on reset circuit when the

power is turned on. (Mask option)

NC pin is always connected to VDD.

Positive power supply pin.
