I'm looking for a list of priorities for the built-in interrupts used by the cortex m7 processor. I'm mainly interested in the ones used by I2C and SPI. I'm using a timer to drive part of my process and I need to ensure the timer has a higher priority than the I2C or SPI processes. I've looked at some of the available documents for the m7 processor and can't find what I'm looking for. Where are the built-in interrupt priorities documented?
