PURPOSE:To cope easily with improvement of a program by providing a flip- flop (FF) which can be set and reset by software. CONSTITUTION:When a macro-instruction is set to a register IR, a sequencer muP sets its (f) part to the 0-th-7-th bit of a register CMAR. On the other hand, when executing this macro-instruction, a flip-flop FF is set (or reset) by software (program), therefore, in accordance therewith, the eighth bit is set to ''1'' (or ''0''). This 0-th-8-th bit execute access to a map part MAP of a control memory CM. As a result, two map parts MAP exist, one of them is selected by setting and resetting the flip-flop FF, and the (f) part of the macro-instruction is expanded equivalently to twice. |
