hi:
is there any Register Protection (REG_PROT)(mpc5744p) software sample or document? thanks!
Solved! Go to Solution.
Hi,
see the Appendix A on page 2843 in the reference manual:
http://www.nxp.com/assets/documents/data/en/reference-manuals/MPC5744PRM.pdf
There's a list of registers which can be protected. There's no INTC_0.BCR, so the lock bits are not implemented and the write access will lead to bus error.
Regards,
Lukas
there is another problem,
CLR_SOFTLOCK32(INTC_0.BCR.R);
GET_SOFTLOCK(INTC_0.BCR.R, lock);
this two function will cause an reset , means we can not access 0xfc043800 ( the Soft Lock Bits area of INIC module). why this is happen?
