BADC: BADC Bus ADC Resolution/Averaging
Bits 10–7 These bits adjust the Bus ADC resolution (9-, 10-, 11-, or 12-bit) or set the number of samples used when
averaging results for the Bus Voltage Register (05h).
SADC: SADC Shunt ADC Resolution/Averaging
Bits 6–3 These bits adjust the Shunt ADC resolution (9-, 10-, 11-, or 12-bit) or set the number of samples used when
averaging results for the Shunt Voltage Register (04h).
BADC (Bus) and SADC (Shunt) ADC resolution/averaging and conversion time settings are shown in Table 5.

MODE: Operating Mode
Bits 2–0 Selects continuous, triggered, or power-down mode of operation. These bits default to continuous shunt and bus
measurement mode. The mode settings are shown in Table 6.

(1) Shaded values are default.
(2) Combination '000' stops converter immediately.
(3) In triggered modes the converter goes to power down. It can be triggered by a write of '1' to bit 14
(One-Shot) in Configuration Register 1 or by the delay scheme of the temperature sensor core. See
Table 7.
(4) Combination '100' stops the converter at conversion end.
