Port 4 Data Direction Register (P4DDR): P4DDR is an 8-bit write-only register that can select
input or output for each pin in port 4.
8-Bit Bus Mode: When all areas are designated as 8-bit-access areas, selecting 8-bit bus mode,
port 4 functions as a generic input/output port. A pin in port 4 becomes an output pin if the
corresponding P4DDR bit is set to 1, and an input pin if this bit is cleared to 0.
16-Bit Bus Mode: When at least one area is designated as a 16-bit-access area, selecting 16-bit
bus mode, port 4 functions as the lower data bus.
P4DDR is a write-only register. Its value cannot be read. All bits return 1 when read.
P4DDR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode
it retains its previous setting.
ABWCR and P4DDR are not initialized in software standby mode. When port 4 functions as a
generic input/output port, if a P4DDR bit is set to 1, the corresponding pin maintains its output
state in software standby mode.
