Description
Synchronous signal input.
When the slave mode is selected, connect these pins to the master
side SYNC OUT 1, and 2 pins.
When the master mode is selected, the input level of these pins are
ignored. Connect these pins to VDD or L-GND at the master mode.
Dimming pulse output.
Connect this pin to the slave side DIM IN pin.
