FUNCTIONAL DESCRIPTION

Normal operation

The SC9314 encodes and transmits address/data to a decoder upon receipt of a trigger signal. The address

codes of SC9314 are always being transmitted as long as power (VDD) is supplied. The transmission function of the

SC9314 is enabled by the D0~D3 pins (active low). The following is the transmission of the SC9314.
