Each of the 4 channels is composed of six blocks:
• A clock selector which selects one of the clocks provided by the clock generator (described in
• A counter clocked by the output of the clock selector. This counter is incremented or
• A comparator used to compute the OCx output waveform according to the counter value and
• A dead-time generator providing two complementary outputs (DTOHx/DTOLx) which allows
• An output override block that can force the two complementary outputs to a programmed
• An asynchronous fault protection mechanism that has the highest priority to override the two
