Make sure that the right combination of LVD and AVD thresholds is used as LVD and AVD
levels are not correlated. Refer to

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).

No effect on SI. AVD interrupts cause the device to exit from Wait mode.
The SICSR register is frozen.
The AVD remains active but the AVD interrupt cannot be used to exit from Halt
mode.
