Hello,
I have a customer who wanted to know if there were any safety mechanisms in place on the on board serial flash? What's the behavior if the CC3120mod happens to be writing to the flash when the reset signal gets asserted?

Hi Munan,
There is no safety mechanism when writing to the serial flash. If nRST or power loss occurs then there is a possibility of corrupted data on the serial flash.
I would encourage your customer to read through this document to learn more about the serial flash system: https://www.ti.com/lit/an/swra515/swra515.pdf
Hi Sabeeh,
Thanks for the feedback! I'll have customer review the app note as well.
