8.9 nCPINSTRVALID
The nCPINSTRVALID signal indicates if the instruction currently on the CPINSTR
bus is valid, and should be decoded by the coprocessor. If nCPINSTRVALID is 1, then
the instruction should not be decoded by the coprocessor and an ABSENT response
should be made for all corresponding Decode cycles for this instruction.
nCPINSTRVALID is the equivalent of the CPTBIT signal in the ARM946E-S and
ARM966E-S processors.
