interrupt priority
The central interrupt manager (CIM) portion of the SYS module manages the interrupt requests from the device
modules (i.e., SPI1 or SPI2, SCI1 or SCI2, and RTI, etc.).
Although the CIM can accept up to 32 interrupt request signals, the VF3x6A device only uses 21 of those
interrupt request signals. The 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 precedences of request channels decrease with ascending channel order in the CIM (0 [highest] and
31 [lowest] priority). For these channel priorities and the associated modules, see Table 5.
