3.3 Undervoltage and Overvoltage Monitoring (MODE=0)

For the following tests, J32 is left open to ground the MODE pin to select 2x Undervoltage + 2x Overvoltage monitoring mode. Voltages are kept in regulation for the pair of channels not shown in the scope capture. Different DLY_TMR settings are shown.
