If no coprocessor is able to process a coprocessor instruction, the instruction is treated
as an UNDEFINED instruction. This allows software to emulate coprocessor
instructions when no hardware coprocessor is present.
By default, CHSD and CHSE must be driven to ABSENT unless the coprocessor
instruction is being handled by a coprocessor. Coprocessor operations are only available
in ARM state.
The cycle timings for coprocessor absent instructions are shown in Table 8-35.
