What is the maximum length of time interrupts can be disabled?

Hey Folks,

 

I'm doing some writing to the Flash and to ensure there aren't interrupt caused issues I'm disabling interrupts during the writes (using _int_disable(); followed at the end of the writes by _int_enable():smileywink:

 

Is there any limit to how long interrupts can be disabled?  Are there any components that I should be aware of?  Along with the standard MCF52223 BSP, I'm also using USB. 

 

I'm asking because the number of writes is dynamic and, if required I can re-enable interrupts to have them serviced and then go back to the writes.

 

Thanx,
