Port 3 Data Direction Register (P3DDR)
P3DDR is an 8-bit readable/writable register that controls the input/output direction of each pin in
port 3. P3DDR is a write-only register. Read data is invalid. If read, all bits always read 1.
Modes 1 and 2: In mode 1 (expanded mode with on-chip ROM disabled) and mode 2 (expanded
mode with on-chip ROM enabled), the input/output directions designated by P3DDR are ignored.
Port 3 automatically consists of the input/output pins of the 8-bit data bus (D
The data bus is in the high-impedance state during reset, and during hardware and software
standby.
Mode 3: A pin in port 3 is used for general output if the corresponding P3DDR bit is set to 1, and
for general input if this bit is cleared to 0. P3DDR is initialized to H'00 by a reset and in hardware
standby mode. In software standby mode it retains its existing values, so if a transition to software
standby mode occurs while a P3DDR bit is set to 1, the corresponding pin remains in the output
state.
