Reset input pin for active “L”.
Input and output pins for the clock generating circuit.
Connect a ceramic resonator or quartz-crystal oscillator between the X
IN
and X
OUT
pins to set
the oscillation frequency.
When an external clock is used, connect the clock source to the X
IN
pin and leave the X
OUT
pin
open.
8-bit CMOS I/O port.
I/O direction register allows each pin to be individually
programmed as either input or output.
