CHAPTER 15 REMOTE CONTROLLER RECEIVER (
(4) Remote controller receive GPHS compare register (RMGPHS)
This register is used to detect the high level of a remote controller guide pulse (short side).
RMGPHS is set with an 8-bit memory manipulation instruction.
RESET input sets RMGPHS to 00H.
(5) Remote controller receive GPHL compare register (RMGPHL)
This register is used to detect the high level of a remote controller guide pulse (long side).
RMGPHL is set with an 8-bit memory manipulation instruction.
RESET input sets RMGPHL to 00H.
RIN
(6) Remote controller DLS compare register (RMDLS)
This register is used to detect the low level of a remote controller data (short side).
RMDLS is set with an 8-bit memory manipulation instruction.
RESET input sets RMDLS to 00H.
(7) Remote controller receive DLL compare register (RMDLL)
This register is used to detect the low level of a remote controller data (long side).
RMDLL is set with an 8-bit memory manipulation instruction.
RESET input sets RMDLL to 00H.
