Loop Closure Detect Debounce Interval LCDI[7:0] is an 8-bit register which sets time interval (decimal value) in digital
format. To convert decimal value to hex value please refer to the beginning of this section (Register Description).
RING Trip Detect Debounce Interval ARTDI[6:0] is an 8-bit register which sets time interval (decimal value) in digital
format. To convert decimal value to hex value please refer to the beginning of this section (Register Description).
This register sets PWM period for the DC/DC converter. Use the following equation to calculate the period.
The PWM period should be set to a value greater than the DC/DC Converter Minimum OFF Time
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.
