PURPOSE:To set an optional pattern to a trigger signal by constituting a titled circuit so that a signal is generated when the result of comparison of the contents of a register which can set an optional signal pattern, and a signal pattern appearing on a signal line in an electronic circuit has become a prescribed condition. CONSTITUTION:A microprocessor 1 reads out and processes successively a program stored in a control storage 2, through a bus line 3, address bus 5 and a data bus 4, and controls an electronic circuit 6. Also, an output 12 of a register 8 which has set a signal pattern 9 by a set signal 10, and a signal pattern sent from the line 3 are compared by a comparing circuit 11. When both of them coincide with each other, a signal is outputted to a trigger outut terminal 13. Also, the signal pattern is set to the register 8 by a command from a high-order connecting device, or a designation from the processor 1. |
