Function Codes for instruction ESTA

All instructions in this table are four bytes in length. The first byte always has a value of X'B2' and the second byte always has a value of X'4A'. The function code is taken from bits 56 through 63 of the second-operand register. Hence it is not part of the assembled instruction's object code. This function code designates the exact pseudo opcode.

    Tyrannosaurus Rex Dinos are not dead. They are alive and well and living in data centers all around you. They speak in tongues and work strange magics with computers. Beware the dino! And just in case you're waiting for the final demise of these dino's: remember that dinos ruled the world for 155-million years!
