The only sure-fire way around this problem is to check the Tempe chip's VMEbus Exception Attributes Register after every write operation and every read that returns an all-1s bit pattern
Just a clarification: Should'nt most applications be terminated upon bus error ?
For those applications, it seems that the overhead for the VME read/write is necessary to be considered only inside the related ISRs or in the related non-ISR routines where the interrupt has to be disabled, which is rare.
