Sym pulse
End of transmission
Matsushita remote control format
The modulated carrier is usually derived from 440kHz and is 1/12 of the frequency with ½
duty cycle.
When data are transmitted repeatedly, the frame cycle is 104.7ms or 240 period.
A frame consists of a syn pulse, a five-bit custom code, six-bit data code, a five-bit inverted
custom code and a six-bit inverted data code.
The timing definitions of the output code waveform are shown below.
