Note: * Lower 20 bits of the address in advanced mode.
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.
Port 2 functions as an address bus.
Mode 5 (Expanded Mode 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.
