Zero-cross control input 1. Select one from four types of zero-cross modes including non-zero-
cross mode. When changing zero-cross modes during operation, set the system so that it
changes at 1 second or more after the rise of CSN signal.

Serialdataoutput
Serial data are outputted from this terminal when CSN pin is "L" level. This terminal becomes
high-impedance state when CSN pin is "H". Since it is an open drain output pin, pull it up
through a resistor to the power supply voltage (to be AVDD or less) of a device to be
connected. Do not allow output current of 1.5mA or over.
I Test terminal Non connection or connect to DGND terminal.

).
And please do not use this terminal output for the drive purpose of an external circuit.
