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 reset, and in hardware standby mode. It retains its prior state 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 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 in software standby mode.
