I am studying the Cortex-M3 technical reference manual.
I have some doubts:- What is the function of each of the 13 general purpose 32-bit registers, R0 to R12?- What does Link Register (LR) do?- What is the function of the xPSR register?- What does the DebugReturnAdress() register do?- What is the function of CONTROL, FAULTMASK, BASEPRI, PRIMASK of register 5b10100?
Thank you in advance!
