R.C. input pin for Single pin oscillator. A resistor is
connected from this pin to VDO and a capacitor to Vss
The ground pin for UM3756
This pin is used to select transmit or receive modes
MODE - VDO : Encoder mode
MODE - Vss : Decoder mode
Receiver input pin. Receives waveform from the detect
circuit
In encoder mode, this pin will transmit waveform; in
decoder mode, this pin will switch to LOW if compa-
rison is OK
