    Hi

    You may use "__enable_irq" and "__disable_irq" to disable/enable all interrupts. I would also recommend to have a look at this page from the ARM documentation that gives some background for this topic (Link).

    Nordic has in there SDK an slightly enhanced version of these functionality that allows nested calls of disable/enable IRQ. These are called "app_util_disable_irq" and "app_util_enable_irq".

    Regards Adrian
