15.3.18 Port output mode registers 1, 6, 7, 12 (POM1, POM6, POM7, POM12)
These registers set the output mode of ports 1, 6, 7, and 12 in 1-bit units.
Set the POM1, POM6, POM7, and POM12 registers by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears the POM1, POM6, POM7, and POM12 registers to 00H.
