I am new to MCF52259 and MQX. I wanted one information regarding QSPI before starting my project.


In the above mentioned chip, we have one QSPI. I wanted to read a time critical data for every 15ms and do firmware upgrade whenever it is available. For both operation I'll be using the same QSPI. Every 15 ms the hardware interrupt will be generated and it is given to QSPI to read the data.


Assume that now the firmware upgrade is going on through the same QSPI and the interrupt also generated with high priority, Now what will happen? please explain to me.
