Interrupt Priority (IEM to CIM)
www.ti.com ......................................................................................................................................................... SPNS108B – AUGUST 2005 – REVISED MAY 2008
Interrupt requests originating from the B768 peripheral modules (i.e., SPI1, SPI2, or SPI3; SCI1 or SCI2; HECC1
or HECC2; 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 precedence 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 7.
