1. When both outputs of a channel are not used (CCxE = CCxNE = 0), the OISx, OISxN, CCxP and CCxNP bits must be kept
cleared.
Note: The state of the external I/O pins connected to the complementary OCx and OCxN
channels depends on the OCx and OCxN channel state and the GPIO and AFIO registers.

Asynchronously: OCx=CCxP, OCx_EN=0, OCxN=CCxNP,
OCxN_EN=0
Then if the clock is present: OCx=OISx and OCxN=OISxN
after a dead-time, assuming that OISx and OISxN do not
correspond to OCX and OCxN both in active state.
Off-State (output enabled with inactive state)
Asynchronously: OCx=CCxP, OCx_EN=1, OCxN=CCxNP,
OCxN_EN=1
Then if the clock is present: OCx=OISx and OCxN=OISxN
after a dead-time, assuming that OISx and OISxN do not
correspond to OCX and OCxN both in active state
