Notes
1.
When P07/XT1 pins are used as the input ports, set processor clock control register (PCC) bit 6 (FRC) to 1.
(Do not use the on-chip feedback resistor of the subsystem clock oscillation circuit.)
2.
When P10/ANI0 to P17/ANI7 pins are used as the analog inputs for A/D converter, set port 1 to input mode.
The on-chip pull-up resistor is automatically disabled.
