IRQ handler in sams70q21

Thu Dec 10, 2015 10:17 am

Hi,MR
We have 20 input sensors that directly connect to PC port on sams70q21. When I use them as irq mode, I find that only the former 7 sensors can call irq handlers, and the others do not response to irq handlers. Why ? Is it the chip limit?
Thank you.
