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 ADCH[4:0] bits in the
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
Notes:
1. X = don’t care.
2. Hi-Z = high impedance.
3. Writing affects data register, but does not affect input.
