The rate of switching is controlled by the dithering controller, and is dependent on the values of the
CLKSRC bit and the SEL[2:0] bits in the HRPDCR register, the contents of the HRPTBH:HRPTBL
registers, and, depending on the value of the HRPMODE bit, the five least significant bits in the HRPPERL
or HRPDCL registers.
