Time
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 0x00_0001. In
the second match between register A1 and the selected time base, the internal counter is set to 0x00_0001
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.
