by another ISR because interrupts are disabled while processing an ISR.
and i think ISR's don't have a priority assoicated with them, rather INTERRUPTS have
a priority (ISR is a software thing!).

can another ISR preempt the current executing ISR! during execution of ISR's are'nt the interrupts disabled?
do ISR's also have priority associated with them???
i think b4 executing an ISR the kernel calls "preempt-disable" (not very sure though....)???

i have read that an ISR can be interrupted by a higer priority ISR, i know it in theory , someone could illustrate with an example ? and please do correct me if i am wrong ?
