Port 6 Data Direction Register (P6DDR)
P6DDR is an 8-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.
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.
