(2) Port mode register (PM7)
This register sets port 7 input/output in 1-bit units.
When using the P74/PCL pin for clock output and the P75/BUZ pin for buzzer output, clear PM74, PM75 and
the output latches of P74 and P75 to 0.
PM7 is set by a 1-bit or 8-bit memory manipulation instruction.
RESET input sets PM7 to FFH.
