Epson ARM720T Manuel D’Utilisation

This chapter describes the test methodology and the CP15 test registers for the ARM720T 

processor synthesized logic and TCM. It contains the following sections:

Coprocessor 15 register c15 of the ARM720T processor is used to provide device-specific test 

operations. You can use it to access and control the following:

•

•

•

You must only use these operations for test. The 

ARM Architecture Reference Manual

 

describes this register as implementation defined.
The format of the CP15 test operations is:

MCR/MRC p15, opcode_1, <Rd>, c15, <CRm>, <opcode_2>

Figure 11-1  CP15 MRC and MCR bit pattern

The L bit distinguishes between an MCR (L set to 1) and an MRC (L set to 0).
