DM648 SPI prescale values

David Meixner

I have a question regarding documentation on the SPI clocking.

In the Bootloader App Report SPRAAJ1D, it states that when FASTBOOT is disabled, the prescale value is set to 0. (Section 1.9.1)

However, the SPI User's Guide states the prescale value is only supported for values >1. (Section 2.1)

My only guess is that these are referring to different prescale registers, but if that is the case, it's not real clear. Could someone please let me know what the valid values are for prescale?

Thanks,
David

David,

Good catch. There is only one prescalar. I think both are referring to same one. Let me check with DM648 SPI expert and get back to you.
