Note:
Make sure that the right combination of LVD and AVD thresholds is used as LVD and AVD
levels are not correlated. Refer to Section 13.3.2 on page 145 and Section 13.3.3 on page
146 for more details.

Interrupts
The AVD interrupt event generates an interrupt if the corresponding Enable Control Bit
(AVDIE) is set and the interrupt mask in the CC register is reset (RIM instruction).
