Note 1: This is the limit to which V
DD may be lowered and the RAM contents will always be retained.
2: If the V
POR or SRVDD parameters are not met, or the application experiences slow power-down VDD ramp
rates, it is recommended to enable and use the BOR.
3: On a rising V
DD power-up sequence, application firmware execution begins at the higher of the VPORREL or
V
BOR level (when BOREN = 1).
