Hello,
I see section 10.6 of spruh77a says to use a CP15 instruction (MCR p15, #0, <Rd>, c7, c0, #4) to put the ARM into wait-for-interrupt sleep mode, but does anyone have example code of how to actually do this? Can a CP15 instruction be embedded in C/C++ code? Again, a complete example of how to put the ARM into WFI state, from within C/C++ code would be really helpful.
thanks,
- Matt.
