condition is still present while writing a Logic [1] to HTF, the
writing has no effect. Therefore, a high-temperature interrupt
cannot be lost due to inadvertent clearing of HTF. Reset
clears the HTF bit. Writing a Logic [0] to HTF has no effect.
Low-Voltage Flag Bit (LVF)
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.
High-Voltage Flag Bit (HVF)
Clear 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.
Overcurrent Flag Bit (OCF)
Reset clears the OCF bit. To clear this flag, write a Logic [1]
to the appropriate overcurrent flag in the SYSSTAT Register.
