FBFALLBACK - incorrect description in TRM spnu499b

Other Parts Discussed in Thread: HALCOGEN

Dear all,

There is an improper bit description in the spnu499b document.

Actual  function Bits 31-16 can be written in privilege mode, bits 13-4 cannot - in the opposite waty of  the current description.

It also means that code generated by Halcogen should be modified - yes, the current value is not an issue in point of functionality view.

Thanks and best regards,

Jiri

    Hi Jiri,

    Bits 31 - 16 do control a feature of the flash interface module. This feature is reserved for use, and ideally these bits should not be written to. HALCoGen writes zeros to these bits, which does not change their function.

    Bits 13 - 4 are not really implemented as there are only banks 0, 1 and 7 on this MCU. So writing to these bits makes no difference.

    Regards, Sunil

    Hello Sunil,

    indeed, it works as you have described - I did not complain about that ;-)

    I just noted the description in TRM spnu499b is not precise - on the Firgure 5-22. That is a minor typo.

    Best regards,

    Jiri
