32.2.10 Port C Data Register 0 (PCDR0)
PCDR0 is a 16-bit readable/writable register that stores port C data. The PC10DR to PC0DR bits
correspond to the PC10 to PC0 pins, respectively.
When a pin function is general output, if a value is written to PCDR0, that value is output directly
from the pin, and if PCDR0 is read, the register value is returned directly regardless of the pin
state.
When a pin function is general input, if PCDR0 is read, the pin state, not the register value, is
returned directly. If a value is written to PCDR0, although that value is written into PCDR0, it
does not affect the pin state. Table 32.15 summarizes PCDR0 read/write operation.
