Block Diagram

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
