Input only
Input/output can be specified bit-wise.
When used as an input port, on-chip pull-up resis-
tor can be used by 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 by software.
Note 2
Port 2
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 by software.

Notes
1.
When using the P07/XT1 pins as an input port, set 1 in bit 6 (FRC) of the processor clock control register
(PCC). The on-chip feedback resistor of the subsystem clock oscillator should not be used.
2.
When using the P10/ANI0 to P17/ANI7 pins as the A/D converter analog input pins, set port 1 to input mode.
The on-chip pull-up resistor is cancelled automatically.
Caution
For pins that also function as port pins, do not perform the following operations during A/D
conversion. If these operations are performed, the total error ratings cannot be kept.
(1) Rewrite the output latch of the output for pins used as a port pin.
(2) Change the output level of pins used as an output pin, even if they are not used as a port pin.
