Figure 26-32. Output PWMCB with Lead Dead-Time Insertion
When operating with trailing edge dead-time insertion, the first match between A1 and the selected time
base sets the output flip-flop to the value of the EDPOL bit and sets the internal counter to 0x000001. In
the second match between register A1 and the selected time base, the internal counter is set to 0x000001
and B1 matches are enabled. When the match between register B1 and the selected time base occurs, the
output flip-flop is set to the complement of the EDPOL bit. This sequence repeats continuously.
