Port 1
8-bit input/output port.
Input/output can be specified bit-wise.
When used as an input port, an on-chip pull-up resistor can be
used by software.

Notes
1.
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.)
2.
When using the P10/ANI0 to P17/ANI7 pins as the A/D converter analog input, port 1 is set to the input
mode. However, the on-chip pull-up resistor is automatically disabled.
Port 7
3-bit input/output port.
Input/output can be specified bit-wise.
When used as an input port, an 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, an on-chip pull-up resistor can be
used by software.
Port 2
3-bit input/output port.
Input/output can be specified bit-wise.
When used as an input port, an on-chip pull-up resistor can be
used by software.
