I am using the hardware IRQ2 line for some low speed comms processing. However it is interfering with the sports interrupt and causing jitter in the audio processing. Does the IRQ line have priority over the SPORTs interrupts ? This is not clear in the manual as the hardware IRQ lines seem to be controlled by a different part of the chip.
How can I arrange it so the SPORTs interrupts always have higher priority over the IRQ interrupts so that they are always executed as a matter of priority ?
