Syntax

MCRR{cond} coproc, #opcode, Rt, Rt2, CRn

MCRR2{cond} coproc, #opcode, Rt, Rt2, CRn

where:

cond

is an optional condition code.

In A32 code, cond is not permitted for MCRR2.

coproc

is the name of the coprocessor the instruction is for. The standard name is pn, where n is an integer whose value must be:

• In the range 0-15 in ARMv7 and earlier.
• 14 or 15 in ARMv8.

opcode

is a 4-bit coprocessor-specific opcode.

Rt, Rt2

are ARM source registers. Rt and Rt2 must not be PC.

CRn

is a coprocessor register.
