Read/Write

This register can only be written if bits WPSWS2 and WPHWS2 are cleared in the 

.

This register acts as a double buffer for the CPOL value. This prevents an unexpected waveform when modifying the polar-
ity value.



The write of this bit is taken into account only if the bit CPOLINVUP is written at ‘0’ at the same time.

0: The OCx output waveform (output from the comparator) starts at a low level.

1: The OCx output waveform (output from the comparator) starts at a high level.



If this bit is written at ‘1’, the write of the bit CPOLUP is not taken into account.

0: No effect.

1: The OCx output waveform (output from the comparator) is inverted.
