3.9
The Interrupt is an active low interrupt. It is set low if any of the following internal faults are detected:
•
•
•
The interrupt will also be set if one of the following status bit conditions is detected:
•
•
•
•
When the interrupt is set low by the detection of one of the status bits, it is set high when the status bits
are read. (READ STATUS DONE) Figure 10 shows the interrupt operation resulting from the fault or
status bit conditions.
A power-on-reset event will reset all of the control and status registers to their default states. A V
event does not reset these registers, but it will signal an interrupt condition and by the action of the timer
that creates the interval “t
