The pin muxing sheet or the Design guideline does not specify which pins can be used as Interrupt GPIOs. Is it safe to assume that all the pins are interrupt capable?
Any GPIO could be used as interrupt source. However, keep in mind the voltage the IO pin supports and POR state before the pinmux is applied. If need to wake up from low power state then you may need to choose Wake capable GPIO.
Noted. And these pins are capable to detect both high/low level interrupts with edge trigger support?
What is the usecase you are trying to do here? Only the GPIOs with “wake” column has capability to be wake up source but any GPIO could be interrupt source.
Yes, it shall be supported.
Currently the usecase is to configure the GPIOs on 40-pin expansion connector J30 on Nvidia EVK kit as interrupt inputs from slave device. No “Wake up source” GPIO is required as of now.
