34.2.2.9.2 SARB interface to PMC
The connection of the PMC to SARB ADC is shown in
connects to the PMC. The PMC contains an analog mux that passes internal voltage nodes
in addition to those given in
PMC digital interface. To convert an internal PMC voltage, the user programs the PMC
analog mux selection, and then programs SARB to convert PMC channel 110. See the
Power Management chapter of this document for more info on additional internal voltages
that can be read by the SARB ADC.
