When used as an input port, on-chip pull-up resistor can be used by
softwareNote 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.
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 by
software.
Port 4
8-bit input/output port.
Input/output can be specified in 8-bit unit.
When used as an input port, on-chip pull-up resistor can be used by
software. Test input flag (KRIF) is set to 1 by falling edge detection.

Notes 1. When using the P07/XT1 pins as an input port, set 1 in the bit 6 (FRC) of the processor clock control
register (PCC). 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. Use of the on-chip pull-up resistor is cancelled automatically.
