1. When both outputs of a channel are not used (control taken over by GPIO controller), 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 GPIO control and alternate function
registers.

OCx output state
Output Disabled (not driven by the timer: Hi-Z)
OCx=0
OCxN=0, OCxN_EN=0
Output Disabled (not driven
by the timer: Hi-Z)
OCx=0
OCxREF + Polarity
OCx=OCxREF XOR CCxP
OCREF + Polarity + dead-
time
Off-State (output enabled
with inactive state)
OCx=CCxP
OCxREF + Polarity
OCx=OCxREF XOR CCxP,
OCx_EN=1
Output disabled (not driven by the timer: Hi-Z).
Off-State (output enabled with inactive state)
Asynchronously: OCx=CCxP, OCxN=CCxNP
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
