Hello,

       When Interrupt occurs during powerpc execution , what does the powerpc do? will it complete the current instruction execution and then jump to ISR or will it suspend the instruction execution , and execute the same instruction after executing ISR?

consider the following instruction under execution  JUMP xxxxx.

so when an interrupt occurs during this instruction execution , does powerpc complete jmp instruction and then go to ISR or it will suspend JMP instruction execute ISR and then

execute JMP instruction again freshly ?

 

does the case same with move instruction ?

Regards
