45.6.3.2 Circular Buffer

The Period register (PER) and the Compare Channels register (CC0 toCC5) support circular buffer operation. When circular buffer operation is enabled, the PER or CCx values are copied into the corresponding buffer registers at each update condition. Circular buffering is dedicated to RAMP2, RAMP2A, and DSBOTH operations.
