Function
Input only
Port 0
7-bit I/O port.
Input/output can be specified bit-wise.
When used as an input port, on-chip pull-up
resistor can be used in software.
Input only
Port 1
8-bit input/output port.
Input/output can be specified bit-wise.
When used as an input port, on-chip pull-up resistor can be used in
software.Note2
Port 2
3-bit input/output port.
Input/output can be specified bit-wise.
When used as an input port, on-chip pull-up resistor can be used in
software.
Port 3
8-bit input/output port.
Input/output can be specified bit-wise.
When used as an input port, on-chip pull-up resistor can be used in
software.
Port 7
3-bit input/output port.
Input/output can be specified bit-wise.
When used as an input port, on-chip pull-up resistor can be used in
software.

Notes 1.
2.
When using the P07/XT1 pins as an input port, set (1) bit 6 (FRC) of the processor clock control register (PCC)
(the on-chip feedback resistor of the subsystem clock oscillator should not be used).
When using the P10/ANI0 to P17/ANI7 pins as the A/D converter analog input, port 1 is set to input mode.
However, on-chip pull-up resistor is not automatically used.
