+Lee Stewart Posted July 27 Share Posted July 27 (edited) First of all, MPY is much more expensive than CLR---not sure it would be better. Secondly, if your code would actually run, it won't work because the last statement has no effect on FAC+6. The autoincrement occurs after the MPY. This should do it: MPY *R3+,*R3+ More importantly (per @Asmusr’s comment below), it will not work because the destination operand must be a register proper. ...lee Edited July 29 by Lee Stewart CORRECTIONS 1 Quote Link to comment Share on other sites More sharing options...
Asmusr Posted July 28 Share Posted July 28 MPY *R3,*R3+ is not valid. The second operand must be a register. 4 Quote Link to comment Share on other sites More sharing options...
