Apply 2.7 V to 5.5 V to the VCC pin. Apply 0 V to
the VSS pin.
Power supply for the comparator
Connect a capacitor between AVCC and AVSS.
Input “L” on this pin resets the MCU.
Connect this pin to VCC via a resistor.
These pins are provided for main clock generation
circuit I/O. Connect a ceramic resonator or a
crystal oscillator between the XIN and XOUT pins.
To use an external clock, input it to the XIN pin
and leave the XOUT pin open.

Analog input pins to comparator
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.
P1_0 to P1_3 also function as LED drive ports.
