Note 1: A common DAC is used for both the CHV_ and IVMAX_ levels.
Note 2: A common DAC is used for both the CLV_ and IVMIN_ levels.
Note 3: The CHV_ and CLV_ levels each have a pair of calibration registers. One is active when using the window comparator; the
other is active when using the differential comparator. The VIN_ level has six calibration registers corresponding to the force
voltage and the five ranges of force current modes of the PMU. The CLAMPHI_, VHH_, IVMAX_, and IVMIN_ levels each
have their own dedicated calibration register. Addressing any of these calibration registers requires device mode settings
(Table 22) as well as the register’s address.
Note 4: The VIOS level is common to both channels. A channel 0 DAC is used to generate VIOS.
Note 5: The IIOS level is common to both channels. A channel 1 DAC is used to generate IIOS.
Note 6: A common DAC is used for both the CLAMPHI_ and VHH_ levels.
