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

If the AVD interrupt is enabled before the V
interrupts will be received: the first when the AVDIE bit is set, and the second when the
threshold is reached.
If the AVD interrupt is enabled after the V
AVD interrupt will occur.
