ELECTRONIC DEVICE HAVING PRINT FUNCTION
Document Type and Number:
Japanese Patent JPS5911438
Kind Code:
A
Abstract:
PURPOSE: To eliminate the need for flag processing, by indicating reexecution of a print routine when the storage of a return address is detected at a detecting means.
CONSTITUTION: A CPU is provided with a stack pointer SP, an arithmetic operating circuit ALU, an address bus AB, and a data bus DB. An ROM stores a control program and is provided with an RAM including a stack S. Whether the return address after the execution of the print routine is stored in the stack S or not is detected from an interruption returning program at the restoration of the interruption. When the storage of the return address is detected, the stack pointer SP indicates re-execution of the print routine.
