Interrupt Priority (IEM to CIM)
www.ti.com ......................................................................................................................................................... SPNS110E – AUGUST 2005 – REVISED MAY 2008
Interrupt requests originating from the A384 peripheral modules (i.e., SPI1 or SPI2, SCI1 or SCI2, RTI, etc.) are
assigned to channels within the 48-channel interrupt expansion module (IEM) where, via programmable register
mapping, these channels are then mapped to the 32-channel central interrupt manager (CIM) portion of the SYS
module.
Programming multiple interrupt sources in the IEM to the same CIM channel effectively shares the CIM channel
between sources.
The CIM request channels are maskable so that individual channels can be selectively disabled. All interrupt
requests can be programmed in the CIM to be of either type:
Fast interrupt request (FIQ)
Normal interrupt request (IRQ)
The CIM prioritizes interrupts. The precedences of request channels decrease with ascending channel order in
the CIM [0 (highest) and 31 (lowest) priority]. For IEM-to-CIM default mapping, channel priorities, and their
associated modules, see Table 6.
