Interrupt Manager API Reference

adi_int_CECUnhook

Description
This function instructs the interrupt manager to unhook (remove) the
given interrupt handler from the interrupt handler chain for the given
IVG.
If the given interrupt handler is the only interrupt handler in the chain,
the CEC is programmed to disable (mask) the given IVG, and the inter-
rupt manager built-in interrupt service routine is removed from the IVG
entry within the event vector table.
If the chain for the given IVG contains multiple interrupt handlers, the
given interrupt handler is simply purged from the chain. If the primary
interrupt handler is removed and there are secondary interrupt handlers
present in the chain, one of the secondary interrupt handlers becomes the
primary interrupt handler.
