4.7.1 CDP, CDP2
Coprocessor data operations.
Syntax
CDP{cond} coproc, opcode1, CRd, CRn, CRm{, opcode2}
CDP2 coproc, opcode1, CRd, CRn, CRm{, opcode2}
where:
cond
is an optional condition code (see Conditional execution on
page 4-4).
coproc
is the name of the coprocessor the instruction is for. The standard
name is
pn
, where
n
is an integer in the range 0-15.
opcode1
is a coprocessor-specific opcode.
CRd, CRn, CRm
are coprocessor registers.
opcode2
is an optional coprocessor-specific opcode.
Usage
The use of these instructions depends on the coprocessor. See the coprocessor
documentation for details.
Note
CDP2
is always unconditional.
Architectures
CDP
is available in ARM architecture versions 2 and above.
CDP2
is available in ARM architecture versions 5 and above.
