How to work with atomic esp32 operations (disabling interrupts)

[Uint64_t]

I have a section of code where it is impossible for an interrupt to work. How can this be implemented? For example, the
instruction 1
instruction 2
disable interrupt
main instruction
enable interrupt
...

You would use a critical section (docs).

Great! But if I need to block the interrupt only on the GPIO13 and do not touch the rest and it should be in the task

?

instruction 1
instruction 2
gpio_set_intr_type(irqPin, GPIO_INTR_DISABLE);
main instruction
gpio_set_intr_type(irqPin, GPIO_INTR_HIGH_LEVEL);

[Uint64_t]

Thanks for the explanation!

Note that on an ESP32, a critical section tends to be better for this, as disabling the IRQ has the race condition that the IRQ may already be in the process of being serviced on the other core. (Additionally, gpio_set_intr_type goes over a shared bus; I'm not sure if without a write fence that write is guaranteed to arrive before the next instruction.)
