1 Note that the Channel 1 normal window comparator continues to function while the device is in differential compare mode, but at a greatly reduced bandwidth.

2 The PPMUx MV/MI inputs to the PPMU go/no-go comparators always come directly from the respective internal PPMU instrumentation amplifiers, not from the PPMU_Mx

output pins (see Figure 143). The internal instrumentation amplifiers are independently configured for either measure voltage (MV) or measure current (MI), depending on

the settings of the PPMU_MEAS_VI_x control bit, as described in Figure 150. When PPMU power is not enabled, the respective go/no-go comparator outputs are locked to

a static low state (see Table 21).
