Hello,

I'd like to know when need to use the Lock bits, of IC_CTRL1 register. When write unlock to the register during initialize, there will be no output for Gate driver. Thanks!

Hi,

Sorry for my late reply.

LOCK bit is optional and you do not need to use. If you not need to use LOCK function, just keep reset value 011b.

If you use LOCK bit, better to "LOCK = 110b" After all register configuration is done.
