7.11.3.4 Switching at the lower of VBAT and Vth level, BSM[1:0] = 11

With this mode switching takes place when VDD falls below the lower 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 VBAT.
