Test and Debug Register c15
You can use register c15 to provide device-specific test and debug operations in 
ARM926EJ-S processors. Appendix B CP15 Test and Debug Registers describes the 
registers and functions available using CP15 c15.This register is defined to be reserved 
for implementation-defined purposes in the ARM Architecture Reference Manual. If 
you write software that uses the device-specific facilities provided by c15, then this 
software is unlikely to be either backwards or forwards compatible.
