4.2
Special events in the Q-SMINT I are indicated by means of a single interrupt output,
which requests the host to read status information from the Q-SMINT I or transfer data
from/to the Q-SMINT I.
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 Q-SMINT I.
The structure of the interrupt status registers is shown in
Figure 73
