NOTE:
LVDF — LVD Flag
The setting of this flag causes an LVD interrupt if LVDE and LVDIE bits
are set and LVDRE is cleared when the supply voltage V
V
EPORT module. Interrupt arbitration in the interrupt service routine is
necessary if both of these interrupts are enabled.
LVDIE — LVD Interrupt Enable
LVDRE — LVD Reset Enable
LVDSE — LVD Stop Enable
LVDE — LVD Enable

The LVDF bit indicates the low-voltage detect status if LVDE is set.
Write a 1 to clear the LVDF bit.
The LVDIE bit controls the LVD interrupt if LVDE is set. This bit has
no effect if the LVDE bit is a logic 0.
The LVDRE bit controls the LVD reset if LVDE is set. This bit has no
effect if the LVDE bit is a logic 0. LVD reset has priority over LVD
interrupt, if both are enabled.
The LVDSE bit controls the behavior of the LVD when the MCU stop
mode is entered if LVDE is set. This bit has no effect if the LVDE bit
is a logic 0.
The LVDE bit controls whether the LVD is enabled.
