6.6 ASC Support
When the ASC pin receives a logic high signal, the output is forced high regardless of the input side pin conditions. The ASC function has higher priority than the input signal and VCC UVLO. The priority of VDD and VEE UVLO, and the overcurrent fault event are higher than the ASC function.
