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

AVD event
No effect on SI. CSS and AVD interrupts cause the device to exit from Wait mode.
The SICSR register is frozen.The CSS (including the safe oscillator) is disabled until
HALT mode is exited. The previous CSS configuration resumes when the MCU is woken
up by an interrupt with “exit from HALT mode” capability or from the counter reset value
when the MCU is woken up by a RESET.
