ARM610 Data Sheet
3-9
When ARM610 takes the undefined instruction trap it performs the following:
1
Saves the address of the Undefined or coprocessor instruction plus 4 in
R14_und; saves CPSR in SPSR_und
2
Forces M[4:0]=11011 (Undefined mode) and sets the I bit in the CPSR
3
Forces the PC to fetch the next instruction from address 0x04
To return from this trap after emulating the failed instruction, use MOVS PC,R14_und.
This will restore the CPSR and return to the instruction following the undefined
instruction.
3.5.6 Vector summary
These are byte addresses, and will normally contain a branch instruction pointing to
the relevant routine.
The FIQ routine might reside at 0x1C onwards, and thereby avoid the need for (and
execution time of) a branch instruction.
The reserved entry is for an Address Exception vector which is only operative when
the processor is configured for a 26-bit program space. See
Compatibility
