Note:
Port 5 Data Direction Register (P5DDR)
P5DDR is an 8-bit write-only register that can select input or output for each pin in port 5.
Bits 7 to 4 are reserved. They cannot be modified and are always read as 1.
Modes 1 to 4 (Expanded Modes with On-Chip ROM Disabled): P5DDR values are fixed at 1
and cannot be modified. Port 5 functions as an address bus.
Modes 5 and 6 (Expanded Modes with On-Chip ROM Enabled): Following a reset, port 5 is
an input port. A pin in port 5 becomes an address output pin if the corresponding P5DDR bit is set
to 1, and an input port if this bit is cleared to 0.
