#85218 Hi team,
I have two devices sharing the HSPI bus. They are both interrupt driven (interrupt drives a GPIO pin) and may also be accessed from the user context. What is the preferred/proper way to disable interrupts (e.g. ETS_GPIO_INTR_DISABLE()) in a way that can be nested so that user-context code can safely access the shared resources?

Regards,
Hinay
