Section 9 I/O Ports
Port 5 Register (PORT5)
PORT5 is an 8-bit read-only register that shows the pin states. It cannot be written to. Writing of
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.
If a port 5 read is performed while P5DDR bits are set to 1, the P5DR values are read. If a port 5
read is performed while P5DDR bits are cleared to 0, the pin states are read.
After a power-on reset and in hardware standby mode, PORT5 contents are determined by the pin
states, as P5DDR and P5DR are initialized. PORT5 retains its prior state after a manual reset, and
in software standby mode.
