Port 0.
2-bit I/O port.
Input/output can be specified in 1-bit units.
Use of an on-chip pull-up resistor can be specified by a software
setting.
Port 1.
8-bit I/O port.
Input/output can be specified in 1-bit units.
Use of an on-chip pull-up resistor can be specified by a software
setting.
Port 3.
4-bit I/O port.
Input/output can be specified in 1-bit units.
Use of an on-chip pull-up resistor can be specified by a software
setting.
Port 6.
