9.3.9.4 Clip Detect

The clip detect is reported on the WARN pin if 100% duty-cycle PWM is reached for a minimum number of PWM cycles set by the Clip Window Register (address 0x23). The default is 20 PWM cycles. If any channel is clipping, the clipping is reported to the pin. The clip detect is latched and can be cleared by I2C. Masking the clip reporting to the pin is possible through I2C. If desired, the Clip Detect can be configured to be non-latching in Clip Control Register (address = 0x22). In non-latching mode, Clip Detect is reported when the PWM duty cycle reaches 100%, and deasserted once the PWM duty cycle falls below 100%.
