P6DDR is a 6-bit write-only register, the individual bits of which specify input or output for the
pins of port 6. P6DDR cannot be read; if it is, an undefined value will be read. Bits 7 and 6 are
reserved.
Setting a P6DDR bit to 1 makes the corresponding port 6 pin an output pin, while clearing the bit
to 0 makes the pin an input pin.
P6DDR is initialized to H'00 by a reset and in hardware standby mode. It retains its prior state in
software standby mode.

P6DR is a 6-bit readable/writable register that stores output data for the port 6 pins (P65 to P60).
Bits 7 and 6 are reserved; they are always read as 0 and cannot be modified.
P6DR is initialized to H'00 by a reset and in hardware standby mode. It retains its prior state in
software standby mode.

Determined by the state of pins P65 to P60.
PORT6 is a 6-bit read-only register that shows the pin states. PORT6 cannot be written to; writing
of output data for the port 6 pins (P65 to P60) must always be performed on P6DR.
