Data Sheet
2.1.2
Special events in the SCOUT are indicated by means of a single interrupt output, which
requests the host to read status information from the SCOUT or transfer data from/to the
SCOUT.
Since only one INT request output is provided, the cause of an interrupt must be
determined by the host reading the interrupt status registers of the SCOUT.
The structure of the interrupt status registers is shown in figure 12.
