Switching at the higher of VBAT or Vth level, BSM[1:0] = 10

With this mode switching takes place when VDD falls below the higher of Vth or VBAT. In

Figure 26, an example is given where the threshold is set to 1.5 V and a single cell battery

is connected to VBAT. In this example, switching to the battery voltage takes place when

VDD falls below Vth.
