Connection terminal for capacitor and resistor constructing bus band filter.
equalizer output terminal.
When there is no zero cross signal until the timer is completed even after setting the timer terminal/data
when there is no signal of the zero cross circuit, the data is forced to be set.
Connect a capacitor of about some 10uF between Vref to VSS (VSS) as a measure against power ripple
where 1/2 VDD voltage for analog ground occurs.
Power voltage terminal.
Serial data and clock input terminal for control.
