Port 5:
Port 5 is an 8-bit I/O port with a user-configurable output type. Port 5 latches have
1s written to them and are configured in the quasi-bidirectional mode during reset. The
operation of Port 5 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 5 also provides various special functions as described below. Port 5 pins used as A/D
inputs must be configured by the user to the high impedance mode.
AD0 (P5.0):
A/D channel 0 input.
AD1 (P5.1):
A/D channel 1 input.
AD2 (P5.2):
A/D channel 2 input.

Port 6:
Port 6 is a 2-bit I/O port with a user-configurable output type. Port 6 latches have
1s written to them and are configured in the quasi-bidirectional mode during reset. The
operation of Port 6 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 6 also provides special functions as described below:
A22 (P6.0):
Address bit 22 of the external address bus.
A23 (P6.1):
Address bit 23 of the external address bus.
