Notes 1. When the P04/XT1 pins are used as input ports, processor clock control register (PCC) bit 6 (FRC) should
be set to 1 (the subsystem clock oscillator incorporated feedback resistor should not be used).
2. When the P10/ANI0 to P17/ANI7 pins are used as A/D converter analog input, port 1 should be set to the
input mode. The on-chip pull-up resistor is not automatically used.
Input/Output is specifiable bit-wise.
When used as the input port, it is
possible to use an on-chip pull-up
resistor in software.
Port 2
8-bit input/output port
Input/output is specifiable bit-wise.
When used as the input port, it is possible to
use an on-chip pull-up resistor in software.
Port 3
8-bit input/output port
Input/output is specifiable bit-wise.
Direct LED drive capability.
When used as the input port, it is possible to
use an on-chip pull-up resistor in software.
