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.
Bit
Modes
1 to 4
Modes
5 to 7
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.
