Alternate Interrupt System
The Alternate interrupt system is enabled by setting the

deassert the nINT output, or clear the interrupt source, and write a ‘1’ to the corresponding Interrupt
Source Flag. Writing a ‘1’ to the Interrupt Source Flag will cause the state machine to check the
Interrupt Source to determine if the Interrupt Source Flag should clear or stay as a ‘1’. If the Condition
to deassert is true, then the Interrupt Source Flag is cleared and nINT is also deasserted. If the
Condition to deassert is false, then the Interrupt Source Flag remains set, and the nINT remains
asserted.
For example, setting the
