Bits 3:0 – DITHER[3:0] Dither Value

These bits configure the fractional adjustment of the on time or off time, according to the Dither Selection (DITHERSEL) bits 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 bits are double-buffered, so the new value is copied when an update condition occurs.
