POUT[7:0]—Port Output Data
These bits contain the data to be driven out from the port pins. The values are only driven
if the corresponding pin is configured as an output and the pin is not configured for alter-
nate 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 set-
ting the corresponding Port Output Control register bit to 1.
