DCN[7:0] DC-DC Converter Period.

This bit sets the PWM period for the dc-dc converter. The range is 3.906 µs (0x40) to

15.564 µs (0xFF) in 61.035 ns steps.

Bit 6 is fixed to one and read-only, so there are two ranges of operation:

3.906 µs–7.751 µs, used for MOSFET transistor switching.

11.719 µs–15.564 µs, used for BJT transistor switching.
