LVF—Low-Voltage Flag Bit
LVF by writing a logic [1] to LVF. If a low-voltage condition is still
present while writing a logic [1] to LVF, the writing has no effect.
Therefore, a low-voltage interrupt cannot be lost due to
inadvertent clearing of LVF. Reset clears the LVF bit. Writing a
logic [0] to LVF has no effect.
HVF—High-Voltage Flag Bit
HVF by writing a logic [1] to HVF. If high-voltage condition is still
present while writing a logic [1] to HVF, the writing has no effect.
Therefore, a high-voltage interrupt cannot be lost due to
inadvertent clearing of HVF. Reset clears the HVF bit. Writing a
logic [0] to HVF has no effect.
OCF—Overcurrent Flag Bit
clears the OCF bit. To clear this flag, write a logic [1] to the
appropriate overcurrent flag in the SYSSTAT Register. See
Figure

This read/write flag is set on a low-voltage condition. Clear
• 1 = Low-voltage condition has occurred.
• 0 = Low-voltage condition has not occurred.
This read/write flag is set on a high-voltage condition. Clear
• 1 = High-voltage condition has occurred.
• 0 = High-voltage condition has not occurred.
This read-only flag is set on an overcurrent condition. Reset
• 1 = High-current condition has occurred.
• 0 = High-current condition has not occurred.
