Operation Description
1.
Powering ON
After powering ON, the S-4561A is initialized by inputting the RESX signal.
In order to prevent the unstable state of the inside of the IC due to momentary stop or gradually raised power voltage
waveform, reset hardware by inputting the RESX signal.
If the S-4561A is not initialized by inputting the RESX signal, the IC may malfunction. Chattering occurring in the RESX
signal may lead to an initialization error. Input the signal free of chattering. Always connect and fix pins P/SX, FNC1 and
FNC2 to V
