P80 is a 1-bit I/O port. Besides serving as an I/O port, it also functions as the chip select input of serial interface
This is the A/D converter reference voltage input pin. This pin is also used for the analog power supply. When
When the A/D converter is not used, connect this pin directly to V
This is the ground potential pin of the A/D converter. Use the same potential as that of the V
This is an active-low system reset input pin.
Resonator connection pins for main system clock.
For an external clock supply, input the clock signal to X1 and its inverted signal to X2.
Resonator connection pins for subsystem clock.
For an external clock supply, input the clock signal to XT1 and its inverted signal to XT2.

This pin functions as a 1-bit I/O port. It can be specified as input or output in 1-bit units using port mode register
8 (PM8).
An on-chip pull-up resistor can be connected by setting pull-up resistor option register 8 (PU8).
This pin functions as the chip select input pin (SS1) of serial interface CSI1.
