PIN FUNCTIONS
3.1
Port Pins (1/2)
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). 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 the input
mode. The pull-up resistor is disabled automatically.
