These bits are input only. Writes to these bits have no effect; reads reflect the state of the GPIO
port 2 bits 4 and 3 respectively.

D104, GPIO Port 1 bits 0 – 4 direction control:

GPIO bits 10 – 14 are inputs

GPIO bits 10 – 14 are outputs

D157, GPIO Port 1 bits 5 – 7 direction control:

GPIO bits 15 – 17 are inputs

GPIO bits 15 – 17 are outputs

D201, GPIO Port 2 bits 0 – 1 direction control:

GPIO bits 20 – 21 are inputs

GPIO bits 20 – 21 are outputs
