Description
This value determines the reset level V RESRISE for rising
V BAT . It is recommended to set this value at least 200mV
higher than V RESFALL .

A reset is generated if Vsupply falls below 2.7V.
(If V VBAT falls below V RESFALL only an interrupt is
generated (if enabled) and the Processor can shut
