In modes 5 to 7, P5DDR is a write-only register. Its value cannot be read. All bits return 1 when
read.
P5DDR is initialized to H'FF in modes 1 to 4, and to H'F0 in modes 5 to 7, by a reset and in
hardware standby mode. In software standby mode it retains its previous setting. Therefore, if a
transition is made to software standby mode while port 5 is functioning as an input/output port and
a P5DDR bit is set to 1, the corresponding pin maintains its output state.
Port 5 Data Register (P5DR): P5DR is an 8-bit readable/writable register that stores output data
for port 5. When port 5 functions as an output port, the value of this register is output. When a bit
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 logic level is read.
Bits 7 to 4 are reserved. They are fixed at 1, and cannot be modified.
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): P5PCR is an 8-bit readable/writable
register that controls the MOS input pull-up transistors in port 5.
Bits 7 to 4 are reserved. They are fixed at 1, and cannot be modified.
