P6DR is an 8-bit readable/writable register that stores output data for the port 6 pins (P67 to P60).

P6DR is initialized to H'00 by a power-on reset, and in hardware standby mode. It retains its prior

state after a manual reset, and in software standby mode.

Note: * Determined by state of pins P67 to P60.

PORT6 is an 8-bit read-only register that shows the pin states. It cannot be written to. Writing of

output data for the port 6 pins (P67 to P60) must always be performed on P6DR.

If a port 6 read is performed while P6DDR bits are set to 1, the P6DR values are read. If a port 6

read is performed while P6DDR bits are cleared to 0, the pin states are read.

After a power-on reset and in hardware standby mode, PORT6 contents are determined by the pin

states, as P6DDR and P6DR are initialized. PORT6 retains its prior state after a manual reset, and

in software standby mode.
