This is about Fault Filter in eflexPWM. Based on MC56F8036 where IPBus clock is 96MHz, PWMA_FFILTn is configured as 0x713 so filter time should be (7+3)*19/96=1.98us. But FFLAG is still set as 1 when input fault pin with a square wave and the width is 1.8us. Is is normal or something wrong?Sutter Zhou
