Bits 3:0 – DITHER[3:0] Dither Value

These bits configure the fractional adjustment of the on-time or off-time according to Dither Selection bits (DITHERSEL) in the Dither Control register (TCD.DITCTRL). 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 doubled buffered so the new value is copied in at an update condition.
