17.6.1
In multi-channel mode the output signals are controlled primarily by the selected phase
sequence (see sequence tables below). Each output is active for two phases and
remains passive for all other phases of a sequence.
The active phases of each output signal may additionally be modulated by T12 or T13.
For unmodulated active phases timer T12 must operate with 100% duty cycle, that is its
offset and compare registers must be cleared, and T13 modulation must be off (bits
CMSELx3 must be cleared). T12 modulation is effective when T12’s duty cycle is
programmed below 100%, T13 modulation is enabled via bits CMSELx3 (see examples
