Note:
Port 2 Data Direction Register (P2DDR)
P2DDR is an 8-bit write-only register that can select input or output for each pin in port 2.
Modes 1 to 4 (Expanded Modes with On-Chip ROM Disabled): P2DDR values are fixed at 1
and cannot be modified. Port 2 functions as an address bus.
Modes 5 and 6 (Expanded Modes with On-Chip ROM Enabled): Following a reset, port 2 is
an input port. A pin in port 2 becomes an address output pin if the corresponding P2DDR bit is set
to 1, and a generic input port if this bit is cleared to 0.
Mode 7 (Single-Chip Mode): Port 2 functions as an input/output port. A pin in port 2 becomes an
output port if the corresponding P2DDR bit is set to 1, and an input port if this bit is cleared to 0.
In modes 1 to 4, P2DDR always returns 1 when read. No value can be written to.
