Notes 1.
When using the P07/XT1 pin 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, use of the pull-up resistor
is cancelled automatically.
