hello i have an opcode of BNE branch which is 1AFFFFF9 and i want to know to which address go this branch i mean how i know what is the next address executed
Indeed.
But note that the decision to execute or not relies only on the flags - there is no relation between the instructions themselves.
In other words, it doesn't matter what instruction set the flags; it's only the state of the flags that matters.
I hope the distinction is not too subtle that it gets lost in translation...
thank you very much for your help
