CC2642R: What is the execution time and resource to execute the BLE application

Manu Balakrishnan

Part Number: CC2642R

Hi,

I am looking for an application where I want to use the ADC interrupt in the M4 core of CC2642R. I want to assign first priority to the ADC interrupt and this ADC ISR will take 34us to execute and will  run every 50 us. I have two questions

1. Is it allowed to make the BLE interrupts having less priority than ADC ISR

2. Whether 16 us time is enough to run the BLE related application function when running with 48MHz clock. If not how much time and M4 resource required for the same. 

Thanks,

Manu

    Manu,

    The BLE Stack must execute as the highest priority in the system. If you change the priority of the BLE Stack, we cannot guarantee stable connectivity as it because much more difficult to maintain the tight timing requirements of the stack.
