Reading from the Port A–H Input Data registers
from the corresponding port pins. The Port A–H Input Data registers are Read-only.
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–H Output Data register
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
–
H Output Data Register (PxOUT)
setting the corresponding Port Output Control register bit to 1.
