3.2.3
Special events in the device are indicated by means of a single interrupt output, which
requests the host to read status information from the device or transfer data from/to the
device.
Since only one interrupt request pin (INT) is provided, the cause of an interrupt must be
determined by the host reading the interrupt status registers of the device.
The structure of the interrupt status registers is shown in
