When bit DDRCx is a logic 1, reading address $0002 reads the PTCx
data latch. When bit DDRCx is a logic 0, reading address $0002 reads
the voltage level on the pin. The data latch can always be written,
regardless of the state of its data direction bit.
the operation of the port C pins.
The ADCH4–ADCH0 bits in the
(ADSCR) defines which PTCx/ADCx pin is used as an ADC input and
overrides any control from the port I/O logic by forcing that pin as the
input to the analog circuitry. See
