Serial communication format (reception)
The figure below shows the “reception” by STLED316S for command/data write sequence.
The STB must be low for 1 µs before the first and last clock rise. The minimum time the STB
must remain low is 9 µs.
The maximum clock frequency is 1 MHz with a duty cycle of 50%. Data set-up and hold time
must be 100 ns.
