Reading from the Port A–C input data registers, returns the sampled values from the
corresponding port pins. See
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.
PIN[7:0]—Port Input Data
Sampled data from the corresponding port pin input.
0 = Input data is logical 0 (Low).
1 = Input data is logical 1 (High).
The Port A–D output data register controls the output data to the pins. See
POUT[7:0]—Port output data
These bits contain the data to be driven to the port pins. The values are only driven if the
corresponding pin is configured as an output and the pin is not configured for alternate
function operation.
0 = Drive a logical 0 (Low).
1= Drive a logical 1 (High). High value is not driven if the drain has been disabled by
setting the corresponding port output control register bit to 1.
