From the output of the element AND 6 signal 1 over the element OR 1 and the driver 7 will reset trigger 8 and set on its inverse output signal 1, which is fed through output 23 to input 10 of device 29-1 and reset its trigger 8. In turn, output 23 of the device 29-1 signal 1 enters

45 to the input 10 of the device 29-2, etc. until the triggers of 8 of all devices are reset. 29.

In addition, the signal O from the direct output of the trigger 8 goes to the output of the prohibition of element 3, as a result of which, the signal 1 appears at its output, allowing the next information word to be written to the register 9 on input 18. In addition, the signal 1 from the output 22 is fed to the input 12 of the device 29-1, its launch to the recording of the information word from the register 9

In this way, the trigger 8 of the remaining devices 29 are reset.

After resetting the trigger 8, the computer 27 sets an information word at input 18 and outputs signal 1 at input 19, with the result that signal 1 appears at the output of prohibition element 3, which allows the information word to be written to register 9 at input 18 and enters through output 21 to the input 12 of the device 29-1, run it to receive the information word. In addition, the signal 1 from the output of the prohibition element 3 enters through the output 26 to the corresponding input of the computer 27, as a result of which it outputs the signal 1 at the input 16 to the element 4, through which the first output of the trigger 8 is set to state 1. From this the output of the trigger 8, the signal 1 is fed to the input element And 5, to the input of the prohibition element 3, is set at its output signal O, and
