This register sets DC/DC Converter Minimum OFF Time. Use the following equation to calculate the period.
DCOFF[7:0] should be programmed to values ≥ 04 hex
The PLL Period (expressed in nsec) which is selected based on the setting of PON:CDCC[7] address (0x22) and
whether the BCLK is binary or decimal.
“ RES ” in the register map means reserved bit(s).
