Abstract
Data for designating a status mode is written beforehand in a data portion of a data-type microinstruction. When power is introduced, first, the data type microinstruction is read. Next, a status-mode setting circuit generates an enable signal. The enable signal is only generated at the initial reading of the data-type microinstruction. The status-mode designating data written in the data portion of the microinstruction is stored in a status-mode memory in response to the enable signal. A central processing unit reads the status-mode designating data that has been stored in the status-mode memory and executes processing conforming to the status mode read.
