Reading from the Port A–C Input Data registers
from the corresponding port pins. The Port A–C Input Data registers are read-only. The
value returned for any unused ports is 0. Unused ports include those missing on the 8- and
28-pin packages, as well as those missing on the ADC-enabled 28-pin packages.
