Note:
Port 8 Data Direction Register (P8DDR): P8DDR is an 8-bit write-only register that can select
input or output for each pin in port 8.
Bits 7 to 5 are reserved. They are fixed at 1, and cannot be modified.
When bits in P8DDR bit are set to 1, P8
P8DDR are cleared to 0, the corresponding pins become input ports.
