Read/Write
Bits 7, 6, 2, and 1 are reserved.
P6DDR is a write-only register. Its value cannot be read. All bits return 1 when read.
P6DDR is initialized to H'80 by a reset and in hardware standby mode. In software standby mode
it retains its previous setting. If a P6DDR bit is set to 1, the corresponding pin maintains its output
state in software standby mode.
Port 6 Data Register (P6DR): P6DR is an 8-bit readable/writable register that stores data for pins
