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.
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
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.
OCF — OVER-CURRENT FLAG BIT
Reset clears the OCF bit. To clear this flag, write a logic [1] to
