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".
