Suppose an interrupt occurs and a table is called initially in the ISR..The
table directs the micro to do an appropriate action defined within the ISR itself..
During its execuiton we have cleared both RBIF and INTF flags to allow more interrupts.. Now suppose we are still in the ISR(doing that 'appropriate' action)..
1.Will another interrupt cause the PC to direct at the table?
2.Or is it necessary that our program has to be out of the ISR(using retfie) to enable further interrupts?
Thanks in advance...
