Interrupt Structure and Logic
Special events in the IPAC are indicated by means of a single interrupt output, which
requests the host to read status information from the IPAC or transfer data from/to the
IPAC.
Since only one INT request output is provided, the cause of an interrupt must be
determined by the host reading the IPAC’s interrupt status registers.
The structure of the interrupt status registers is shown in figure 78.
