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–C Output Data register
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.
The LED Drive Enable register
C pin must first be enabled by setting the Alternate Function register to select the LED
function.
