Output protection pins.
They could be connected independently
or to LED supplies (VLED).
Power supply terminal.
Ground terminal.
Driver ground
Serial input for grayscale data.
Serial output for grayscale data.
Synchronous clock input for serial data
transfer. The input data of SIN is
transferred at rising edges of DCK.
If SELBK is H, shift-in date would be
stored in the 8-bit BANK 1.
If SELBK is L, shift-in date would be
stored in the 6-bit BANK 0.
When LAT_B converts from H to L,
grayscale data in both shift register
banks are latched.
Clock input for PWM operation.

Input terminal of output enable. All
outputs are OFF when EN_B is H.
The IC is initialized when RST_B low.
There is an internal pull-up on this pin.
This pin couldn’t be floating. Before using
the IC, it must be reset first. If each
channel is assigned to drive multiple
LEDs, IC should be reset before each
LED data latch to prevent from flashing.
