Voltage Regulator Over-voltage Condition - This status bit indicates an over-voltage warning is present for at least one of the
main voltage regulators (VDD or VDDX). Reading the register will clear the VROVI flag if present. See
for details. Note: This feature requires the trimming of
effective. Untrimmed devices may issue the VROVC condition including the LS turn off at normal operation.
0 - No Voltage Regulator Over-voltage Condition present.
1 - Voltage Regulator Over-voltage Condition present.
High Temperature Condition - This status bit indicates a high temperature warning is present for the Voltage regulators
(VDD/VDDX). Reading the register will clear the HTI flag if present. See
0 - No High Temperature Condition present.
1 - High Temperature Condition present.
High Voltage Condition - This status bit indicates a high voltage warning for VS2 is present. Reading the register will clear the
HVI flag if present. See
0 - No High Voltage Condition present.
1 - High Voltage Condition present.
Low Voltage Condition - This status bit indicates a low voltage warning for VS1 is present. Reading the register will clear the
LVI flag if present. See
0 - No Low Voltage Condition present.
1 - Low Voltage Condition present.
Low Battery Condition - This status bit indicates a low voltage warning for VSENSE is present. Reading the register will clear
the LBI flag if present. See
0 - No Low Battery Condition present.
1 - Low Battery Condition present.
