This register is used to detect the high level of remote controller data 0 (long side).
RMDH0L is set with an 8-bit memory manipulation instruction.
RESET input sets RMDH0L to 00H.

(10) Remote controller receive DH1S compare register (RMDH1S)

This register is used to detect the high level of remote controller data 1 (short side).
RMDH1S is set with an 8-bit memory manipulation instruction.
