Loss of VDDSRAM sticky. These status bits indicate whether a VDDSRAM supply failure oc-
curred. In addition, when the power is turned on for the first time, VDDSRAM rises and these
bits are set. The LVSRS bits are cleared by writing them to ones. A write of zero has no effect
on these bits.
0 = No VDDSRAM supply failure was detected
1 = VDDSRAM supply failure was detected
VDDSRAM detector disable.
0 = VDDSRAM detection circuit is enabled
1 = VDDSRAM detection circuit is disabled
