Section 9 I/O Ports
P5DDR is a write-only register. Its value cannot be read. All bits return 1 when read.
P5DDR is initialized to H'F0 by a reset and in hardware standby mode. In software standby mode
it retains its previous setting, so if a P5DDR bit is set to 1, the corresponding pin maintains its
output state in software standby mode.
Port 5 Data Register (P5DR)
P5DR is an 8-bit readable/writable register that stores output data for pins P5
in P5DDR is set to 1, if port 5 is read the value of the corresponding P5DR bit is returned. When a
bit in P5DDR is cleared to 0, if port 5 is read the corresponding pin level is read.
Bit
Initial value
Read/Write
Bits 7 to 4 are reserved. They cannot be modified and are always read as 1.
P5DR is initialized to H'F0 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
Port 5 Input Pull-Up MOS Control Register (P5PCR)
Bit
Initial value
Read/Write
P5PCR is an 8-bit readable/writable register that controls the MOS input pull-up MOS transistors
in port 5.
