255 b00001011 When in the Low-Voltage Sleep mode (entry due to low voltage
and Sample mode), there are four methods for waking up. They
are voltage level, current level, SMBus activity and I/O pin
activity. This value defines which wake-up functions are
enabled and also the voltage wake-up level. The table below
indicates the appropriate setting. Note that the setting is
independent of the number of cells or their configuration.
