Notes
1. When the P07/XT1 pin is used as an input port, set bit 6 (FRC) of the processor clock control register
(PCC) to 1 (do not use the internal feedback resistor to the subsystem clock oscillator).
2. When pins P10/ANI0 to P17/ANI7 are used as an analog input of the A/D converter, the internal pull-
up resistor is automatically disabled.
