RT117x: where is the FORCE_COLD_BOOT fuse reflected?

On the Ref Man I read:

Screenshot_2023-04-11_18-15-01.png

the FORCE_COLD_BOOT should be reflected in SRC_SBMR...

I looked for SRC_SBMR and found two registers, but in neither of them do I seem to see the bit reflected by the FORCE_COLD_BOOT fuse.

Could you point me to which register and which bit I find it in?

best regards

Max

Hi @mastupristi ,

For RT1170, I think this fuse bit is not touched by ROM. You can ignore it.

Is this your feeling or do you have written confirmation in some document?
Because the only document I have available says the fuse is there and it's reflected somewhere on SRC.

Then I suggest removing the description of that fuse from both the Refernce Manual and the Security Refernece Manual
