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

channel regardless of other channels. In the same way, the clear registers

(OSC and OSCUPD) disable the override of the outputs of a channel regardless of other
channels.
By using buffer OSSUPD and OSCUPD registers, the output selection of PWM outputs is done
synchronously to the channel counter, at the beginning of the next PWM period.
By using OSS and OSC registers, 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 OS.
While overriding PWM outputs, the channel counters continue to run, only the PWM outputs are
forced to user defined values.
