Problem with "Concerto F28M36x Technical Reference Manual" documentation (GPIO part)

Hello,

I have some doubts about the concerto F28M36 GPIO documentation (SPRUHE8B).

In section 4.2.7.40 bits 0-3 of GPCDAT register are marked as "Reserved". The problem is, I have not found the DATA bits of GPIO from 64 to 67.

If we follow the numbering logic it should be placed in GPCDAT bit 0 to 3.

It tried to write in these bits and I can't change the GPIO64 logic level on the Experiment Kit.

I think it is a problem in the documentation, but is there someone from TI that can confirm that point?

Thanks

Dimitri

    Dimitri,

    It looks like you are correct.  The header file and documentation will need to be updated.  I will contact the appropriate people to get this corrected.

    For now you can make the following edit to the header file (F28M36x_Gpio.h) to gain access to the GPIOs:

    Hope this helps!
