TLC6C5724-Q1: Will the LED driver work normally or keep a sink current if there is no/abnormal SPI signal

Part Number: TLC6C5724-Q1

Hi team

I would like to ask that will the LED driver work normally or keep a sink current if the SPI signal is abnormal(like LATCH,GCLK,BLANK signal) or there is no input SPI signal? Or will it directly not work?

In my opinion, the LED driver may have a initial work status without SPI communication signal right?
