About E-Fuse controller of TMS570LS31x

Can CPU read internal registers which loaded E-Fuse values and the E-Fuse values?

    Not the values. These are for TI use and not public anyway.
    But for diagnostic purposes the EFUSE controller has error detection and this detection can be self-tested.

    If you want to store permanent data - there is an OTP area in the FLASH that is available for customer use.
    You can put almost what you want there. [I think the AJSM key goes right at the beginning of that OTP sector though ---- there so be careful about not locking yourself out by programming it accidentally.]

    When EFUSE controller detected an error, I'd like to know influence to a microcomputer.
    What kind of influence is there in CPU function?
    What kind of influence is there in the reading and writing function of the flash and the SRAM memory?
    Please also inform me about other influence.
