16-bit Constant Current LED Sink Driver with Error Detection
Resuming to Normal Mode

Each time the system controller sends the sequence patterns shown above, MBI5027 can
resume to the Normal mode. During this phase, the system controller can still send data
through SDI pin.
The state of OE (ED2) and LE(ED1) is sampled by the rising edge of each CLK. We use “0”
and “1” to represent the state of “Voltage Low” and “Voltage High” respectively. The states of
the successive five OE (ED2) and LE(ED1) are (1, 0), (0, 0), (1, 0), (1, 0) and (1, 0).
