TMS320F28379D: C28x/CLA acces to the ADC

Part Number: TMS320F28379D

Hello,
I have a question regarding the access of the C28x and the CLA to the ADC. In my application the C28x and the CLA needs access to the same ADC result register.

What happens if the C28x and the CLA accesses the same time to the same ADC result register? Is this allowed?

Thank you very much
Ralf

    Hi Ralf,

    For most registers and memory, the CPU and CLA will arbitrate, briefly delaying the read to one of the requesting sources.  However, the ADC results are intentionally multi-port read to allow simultaneous reads from all masters without delay.
