Bits 3:0 – DITHER[3:0] Dither Value

This bit field configures the fractional adjustment of the on-time or off-time, according to the Dither Selection (DITHERSEL) bit field in the Dither Control (TCDn.DITCTRL) register. The DITHER value is added to a 4-bit accumulator at the end of each TCD cycle. When the accumulator overflows, the frequency adjustment will occur.

The DITHER bit field is double-buffered, so the new value is copied when an update condition occurs.
