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 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 Port A-K data direction registers (see
either inputs or outputs.
DD[7:0]—Data Direction
These bits control the direction of the associated port pin. Port alternate function operation
overrides the data direction register setting. 
0 = Output
Data in the Port A-K output data register is driven onto the port pin.
1 = Input
The port pin is sampled and the value written into the Port A-K input data register. The
output driver is high impedance.
