Apply 2.2 V to 5.5 V to the VCC pin. Apply 0 V to the VSS pin.
Input “L” on this pin resets the MCU.
Connect this pin to VCC via a resistor.
These pins are provided for XCIN clock generation circuit I/O.
Connect a crystal oscillator between the XCIN and XCOUT
pins.

CMOS I/O ports. Each port has an I/O select direction
register, allowing each pin in the port to be directed for input
or output individually.
Any port set to input can be set to use a pull-up resistor or not
by a program.
