Slave Mode
Slave Mode is selected when M/S pin is set at Low level. The slave mode operation is as follows:
• The internal dimming circuit is ignored.
• The pulse width of SEG1 to 32 are controlled by the pulse width of DIM IN signal.
• The segment Latch1 to 3 corresponding to GRID1 to 3 are selected by SYNC IN1 and SYNC IN2
• The output levels of GRID1 to 3 are set at High level. The output levels of DIM OUT, SYNC
