as an input source.
This is a programmable 4-bit I/O port (PORT6).
Input and output can be specified in bit units.
Connection of an on-chip pull-up resistor can be
specified in 4-bit units by software.
This is a 4-bit I/O port (PORT7).
Connection of an on-chip pull-up resistor can be
specified in 4-bit units by software.
This is a 4-bit I/O port (PORT8).
Connection of an on-chip pull-up resistor can be
specified in 4-bit units by software.
These pins are also used as 1-bit I/O port (BIT
PORT) segment output pin.
