SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER for
INFRARED REMOTE CONTROL TRANSMITTER
CARRIER GENERATING CIRCUIT
The 4551 Group has a carrier generating circuit that generates
the transfer waveform by dividing the system clock (STCK) for
each remote control carrier wave. Each carrier waveform can be
output by setting the carrier wave selection register (C1).
Also, timer 1 can auto-control the carrier wave output from port
CARR by setting the carrier wave output control register (C2).
