The B0-D0 pair is configured as complimentary with a deadband of 1usec (500nsec each side). The complimentary pair works fine overall
The complimentary is enabled/activated inside the PWM period completion ISR through TRDOER1 register.
The Duty value is loaded in buffered mode.The Duty is forcefully written 0 in PWM period Isr at the same instant when complimentary is activated.
Issue : sporadically both the channels turn ON for 2 usec (the instant is captured in the attached screenshot). Root cause of this issue is not known
Please find the attached screenshot of the waveforms captured.(Pink – slave channel : Yellow – master channel)
Any updates on this problem? Were you able to fix or at least know what's causing this?
