Advanced features for motor control

Note:

Dead time insertion is enabled by setting both CCxE and CCxNE bits, and the MOE bit.

When only OCxN is enabled (CCxE=0, CCxNE=1), it is not complemented and becomes

active as soon as OCxREF is high. For example, if CCxNP=0 then OCxN=OCxRef. On the

other hand, when both OCx and OCxN are enabled (CCxE=CCxNE=1) OCx becomes

active when OCxREF is high, whereas OCxN is complemented and becomes active when

OCxREF is low.
