Advance Information
3. Read the interrupt status register(s) identified in step 2. The bits which are set in these registers identify the
source of the interrupt. As each register is read, it is cleared (all bits set to 0). When all interrupt status
registers are cleared, the interrupt vector goes to zero and the IRQ pin returns to logic high.
