DAISY CHAINING OF INTERRUPTING DEVICES |
摘要 |
A microprocessor controlled cathode ray tube display system has a plurality of peripheral devices all connected in common to a system bus. Apparatus in each peripheral device activates a single interrupt signal. A single acknowledge response signal to all the devices enables the interrupting device to place its address signals on the system bus thereby initiating a firmware routine for making the interrupting device operative with the system. |
