Hello
AM3354BZCZAI00 This CPU is now used, the original use is GPIO3_21 interrupt.
Because the project has relatively high requirements for interruption, it is almost impossible to lose the interruption. With this ordinary IRQ interrupt, about 2000 interrupts will lose about 4 or so.
Mapping this IRQ interrupt to the FIQ interrupt should not cause the interrupt to be lost.
I would like to ask this CPU can use FIQ interrupt? There is currently no way to find out on the Internet.
Do you have any relevant examples?
--Thanks and Best Regards
