Port 5 Data Direction Register (P5DDR)
P5DDR is an 8-bit write-only register, the individual bits of which specify input or output for the
pins of port 5. Bits 7 to 4 are reserved. P5DDR cannot be read; if it is, an undefined value will be
read.
Setting a P5DDR bit to 1 makes the corresponding port 5 pin an output pin, while clearing the bit
to 0 makes the pin an input pin.
P5DDR is initialized to H'0 (bits 3 to 0) by a power-on reset, and in hardware standby mode. It
retains its prior state after a manual reset, and in software standby mode.
Port 5 Data Register (P5DR)
P5DR is an 8-bit readable/writable register that stores output data for the port 5 pins (P5
Bits 7 to 4 are reserved; they return an undetermined value if read, and cannot be modified.
P5DR is initialized to H'0 (bits 3 to 0) by a power-on reset, and in hardware standby mode. It
retains its prior state after a manual reset, and in software standby mode.
