Section 9 I/O Ports
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.
Port 4 Data Register (P4DR)
P4DR is an 8-bit readable/writable register that stores output data for pins P4
in P4DDR is set to 1, if port 4 is read the value of the corresponding P4DR bit is returned. When a
bit in P4DDR is cleared to 0, if port 4 is read the corresponding pin level is read.
Bit
Initial value
Read/Write
P4DR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
Port 4 Input Pull-Up MOS Control Register (P4PCR)
P4PCR is an 8-bit readable/writable register that controls the MOS input pull-up transistors in port
4.
Bit
Initial value
Read/Write
In mode 7 (single-chip mode), and in 8-bit bus mode in modes 1 to 6 (expanded modes), when a
P4DDR bit is cleared to 0 (selecting generic input), if the corresponding P4PCR bit is set to 1, the
input pull-up MOS transistor is turned on.
P4PCR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
