Reserved. Always write bits to 0.

ADC_IIR_TAU

0x00

read-write

Determines the time constant used in the ADC's averaging

low-pass IIR filter voltage reading. Time constant =

2^(ADC_IIR_TAU)

2:0

ADC_INTERVAL

0x00

read-write

If ADC_INTERVAL > 0, automated ADC measurements

are enabled in EM0 and EM2. The automated measure-

ments will be triggered when the count of all pulse events

in all of the enabled converters is equal to 2^(ADC_IN-

TERVAL+3). To ensure that measurements occur even

when pulse events are very infrequent, an ADC measure-

ment will be triggered approximately every ~400msec at a

minimum when ADC_INTERVAL > 0, regardless of the

pulse event count.

If ADC_INTERVAL > 0 and BB_CTRL2.BB_IPK_NOADJ =

0, automatic inductor peak current adjustments in boost

mode will be enabled.

If ADC_INTERVAL = 0, there will be no automatic ADC

measurements enabled, which means NO temperature-

dependent bias refresh and/or boost-mode automated in-

ductor peak current adjustments. In addition, any flags or

bits requiring the ADC (e.g., STATUS_G.VDD_LOW and

STATUS_G.TEMP_FAULT) will not be updated.
