Abstract
PURPOSE: To collect data without modifying a microprogram by executing a main microprogram on the basis of the contents of the current address after executing a data-collection program routine by interruption processing.
CONSTITUTION: Once data-collection request signal S1 is input to stacker control circuit 3, data D1 from current-address register 4 are stored in stacker 2 and the initial address of a preset data-collecting routine is output from stacker 2 as data D2. Output address ADD from address change-over circuit 5 is input to a fixed unit and also to +1 circuit 6. After the data-collecting routine is executed by interruption processing, the current address stored in stacker 2 is read out and, after being increased by one, stored in current-address register 4, so that the next step of the main microprogram will be executed.
