Dear all !
i am trying to use a timer interrupt to call a function in an ARM7 platform.i hope this timer interrupt can happen in a 320 microseconds interval.however,i found that when i make the interval less than 11 milliseconds exception happened.
11 milliseconds is too slow for me.why this happened?can somebody help?many thanks!

additional:i made a big mistake in my description, mixing up microseconds with milliseconds. really sorry.
