The figure below shows the settling time of the parallel Pin
PMU measurements and the subsequent conversion times
needed for the multiplexed analog value conversions
performed by the Board ADC.
Figure 22 Multiplexed AD Conversion of Parallel Pin PMU Measurements
Settling of signals costs time. However, the Pin PMU
signals can settle in parallel (parallel value measurement)
saving a lot of settling time. Next, the measurement PMU
performs value measurements in serial.
