PTB0–PTB7 and PTD0–PTD3 are general-purpose I/O pins that are
shared with the ADC channels. The channel select bits (ADC Status and
Control register, $003C), define which ADC channel/port pin will be used
as the input signal. The ADC overrides the port I/O logic by forcing that
pin as input to the ADC. The remaining ADC channels/port pins are
controlled by the port I/O logic and can be used as general-purpose I/O.
