Note:
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.
Modes 1 to 5 (Expanded Modes): When all areas are designated as 8-bit-access areas by the bus
controller’s bus width control register (ABWCR), selecting 8-bit bus mode, port 4 functions as an
input/output port. In this case, a pin in port 4 becomes an output port if the corresponding P4DDR
bit is set to 1, and an input port if this bit is cleared to 0.
When at least one area is designated as a 16-bit-access area, selecting 16-bit bus mode, port 4
functions as part of the data bus, regardless of the P4DDR settings.
Mode 7 (Single-Chip Mode): Port 4 functions as an input/output port. A pin in port 4 becomes an
output port if the corresponding P4DDR bit is set to 1, and an input port if this bit is cleared to 0.
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.
