Integrated Programmable Interrupt Controller (IPIC)

By programming the system interrupt mask registers, SIMSRx and SEMSR, the user can mask interrupt

requests to the core. Each SIMSRx and SEMSR bit corresponds to an interrupt source. To enable an

interrupt, set the corresponding SIMSR or SEMSR bit. When a masked interrupt source has a pending

interrupt request, the corresponding SIPNRx or SEMSR bit is set, even though the interrupt is not

generated to the core. The user can mask all interrupt sources to implement a polling interrupt servicing

When an interrupt source has multiple interrupting events, the user can individually mask these events by

programming a mask register within that particular block.

multiple interrupting events.
