56F8357 Technical Data
Preliminary
5.3.3
Fast interrupts are described in the
DSP56800E Reference Manual
. The interrupt controller
recognizes fast interrupts before the core does.
Fast Interrupt Handling
A fast interrupt is defined (to the ITCN) by:
1. Setting the priority of the interrupt as level 2, with the appropriate field in the IPR registers
2. Setting the FIMn register to the appropriate vector number
3. Setting the FIVALn and FIVAHn registers with the address of the code for the fast interrupt
When an interrupt occurs, its vector number is compared with the FIM0 and FIM1 register values.
If a match occurs, and it is a level 2 interrupt, the ITCN handles it as a fast interrupt. The ITCN
takes the vector address from the appropriate FIVALn and FIVAHn registers, instead of generating
an address that is an offset from the VBA.
The core then fetches the instruction from the indicated vector adddress and if it is not a JSR, the
core starts its fast interrupt handling.
