BUCK FUNCTION REGISTER (BFCR) – 0x38
This register allows the Buck switcher clock frequency to be spread across a wider range, allowing for less Electro-magnetic
Interference (EMI). The spread spectrum modulation frequency refers to the rate at which the frequency ramps up and down,
centered at 2 MHz.
