LED Drivers - Configurable Current Sinks. Can be assigned to GroupA or GroupB

B3

D1B / INT

LED Driver/ ALS Interrupt - GroupB Current Sink or ALS Interrupt Pin. In ALS Interrupt

mode, a pull-up resistor is required. A '0’ means a change has occurred, while a ‘1’

means no ALS adjustment has been made.
