In considering some MultiTasking ideas, mainly Flash writing; you said to turn off interrupts.
Does INTERRUPT(0) turn off the SUB INTERRUPT(s) that I create?? .. and then back on with (1)??
Thanks

The multitask timer should be switched off (I think there is an example of that in the original).

INTERRUPT(0) turns of all interrupts controlled by the I bit in the CPSR of the ARM, and the systick interrupt

So that would be a sledge hammer way to do it. I have no idea whether the ROM routine we call (written by NXP) uses interrupts, but I kind of doubt it
