Power-Failure Interrupts
The
supervisor. A power-failure interrupt occurs when
0.05 V. This advanced warning allows the program to perform some
emergency processing before an unwanted power-down occurs.
The following example shows how to handle a power-failure interrupt.
You also need to add the following line to
Interrupt Priorities
Table C-6 lists the interrupt priorities.
