6.4.3 Low Power Modes
6.4.3.1 Interrupts
The AVD interrupt event generates an interrupt if
the corresponding Enable Control Bit (AVDIE) is
WAIT
HALT
Mode
No effect on SI. AVD interrupts cause the
device to exit from Wait mode.
The CRSR register is frozen.
Description
set and the interrupt mask in the CC register is re-
set (RIM instruction).
