Arbitration when the ADC read and write has collided (Device : F2407 & F2812)

Hi, 

 I understood that F28335 is not possible to get invalid data from the result registers.

e2e.ti.com/.../118564

Is ADC arbitration of F2407&F2812 the same as this arbitration?

Best regards,

Mino.M

    Mino,

    I do not know the order of the arbitration on F2407 and F2812 devices, but you will not get invalid data from the ADC results register. You will either read the old result, or the new result, depending on whether the read or the write gets priority. I suspect the write gets priority, but I suspect it really doesn't matter for the application. You just want to make sure you don't get corrupted results.
