Output Override
The two complementary outputs DTOHx and DTOLx of the dead-time generator can be forced
to a value defined by the software.

PWM_OSCUPD) disable the override of the outputs of a channel regardless of other channels.
By using buffer registers PWM_OSSUPD and PWM_OSCUPD, the output selection of PWM
outputs is done synchronously to the channel counter, at the beginning of the next PWM period.
By using registers PWM_OSS and PWM_OSC, the output selection of PWM outputs is done
asynchronously to the channel counter, as soon as the register is written.
The value of the current output selection can be read in PWM_OS.
While overriding PWM outputs, the channel counters continue to run, only the PWM outputs are
forced to user defined values.
(PWM_OSS and PWM_OSSUPD) enable the override of the outputs of a channel
