Port 2: Port 2 is a 2-bit I/O port with a user-configurable output type. Port 2 latches are configured in the
quasi-bidirectional mode and have either ones or zeros written to them during reset, as determined by
the PRHI bit in the UCFG1 configuration byte. The operation of port 2 pins as inputs and outputs
depends upon the port configuration selected. Each port pin is configured independently. Refer to the
section on I/O port configuration and the DC Electrical Characteristics for details.
Port 2 also provides various special functions as described below.
Ground: 0V reference.
Power Supply: This is the power supply voltage for normal operation as well as Idle and
Power Down modes.
