    RE: CCS/UCD3138128: How to configure cmd file for 64k flash size

    I'd also suggest that you look at zero out integrity word, or clear integrity word. It's case 12 in the software interrupt. Somewhere in the code, it will pick an address to write to, probably 7ff8 or 7ffc. You will need to change it to fff8...

    RE: CCS/UCD3138: The confirmation ABORT

    The abort exceptions also have their own stack area and stack pointers. You need to initialize them as well. Some of our EVMs do not, because we are happy to just reset. If the stack pointers are not initialized, they will most likely point to an illegal...

    RE: UCD3138: Default mode on each pin when POR

    I don't know where you got those last charts. I hope it's not a TI document, as it has some issues, for example all DPWMs are always low after reset. It's a bit more complicated, because on some devices, all GPIO pins are pulled low during...
