PI DATA [7:0]
Note 10: Serial data input has no effect on the ON/OFF state of the outputs.
Note 11: The BLANK signal has not effect on parallel data input. The PWM pulse can be controlled using the BLANK signal.

When the SI LATCH signal holds the serial data, the output current values and output pulse width are affected.
It is recommended that, on completion of data transfer, BLANK be set to High and outputs be turned OFF.
