Port 7 Data Direction Register (P7DDR)
P7DDR is a 6-bit write-only register, the individual bits of which specify input or output for the
pins of port 7. P2DDR cannot be read; if it is, an undefined value will be read. Bits 7 and 6 are
reserved.
Setting a P7DDR bit to 1 makes the corresponding port 7 pin an output pin, while clearing the bit
to 0 makes the pin an input port.
P7DDR is initialized to H'00 (bits 5 to 0) by a reset, and in hardware standby mode. It retains its
prior state in software standby mode.
