4.4 Coprocessor model interface

The coprocessor model interface is defined in

armul_copro.h

. The basic coprocessor

functions are:

• ARMulif_InstallCoprocessorV5 on page 4-16

• LDC on page 4-17

• STC on page 4-18

• MRC on page 4-19

• MCR on page 4-20

• MRC on page 4-19

• MCR on page 4-20

• MCRR on page 4-21

• MRRC on page 4-22

• CDP on page 4-23.

In addition, two functions are provided that enable a debugger to read and write

coprocessor registers through the Remote Debug Interface (RDI). They are:

• read on page 4-24

• write on page 4-25.

If a coprocessor does not handle one or more of these functions, it must leave their

entries in the

ARMul_CPInterface

structure unchanged.
