can be reconfigured via the SPI if desired, if an alternate range is needed. Care should be taken when changing SWxHI bit to
avoid unintended jumps in the switcher output. The SWxHI setting applies to Normal, Standby, and DVS set points for the
corresponding switcher.

Since the startup default values of the buck switchers are dependent on the state of the PUMS pin, the SWxHI bit settings will
Note that the following efficiency curves were measured with the MC13892 in a socket.

Output range not available for SW1. SW1 output range is 0.600-1.375, therefore SW1HI = 1 does not apply to SW1. The SW1HI bit
should always be set to 0.
