ATMEGA324P 8-Bit Microcontroller

2.3.1 VCC Digital supply voltage. 2.3.2 GND Ground. 2.3.3 Port A (PA7:PA0) Port A serves as analog inputs to the Analog-to-digital Converter. Port A also serves as an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port A output buffers have symmetrical drive characteristics with both high sink and source capab.
