On each positive going transition of the scan clock input, the internal digit select counter is incremented and new BCD data transferred to the latch data input bus. On each negative going transition of the scan clock input, a monostable multivibrator (IC15/2) is triggered and produces an output pulse at approximately 10 ⁇ sees to enable the digit select outputs of the counter and 5. hence pulse the required latch strobe line to store the BCD digit currently on the latch date input bus.

  • HP97S calculator may be initiated in two ways and is dependent upon the mode in which the system is operating 20. as defined by the state of Flag 2.
  • the two flip-flops comprising IC21 control the initiation of data input to the calculator.
  • IC21/1 When IC21/1 is set r either by the ENTER key from the keyboard or by the end of pump operation, it indicates that data is 5. ready in the latches for transfer to the calculator.
  • the LOAD line to the calculator On the next rising edge of OSC, the LOAD line to the calculator is set high. The calculator indicates that data is being accepted by setting LE low, which resets the data ready and load flip flops (IC21) .
  • the end of pump operation is detected by sensing the removal of supply to the pump motor caused by the switch operated when the nozzle is placed back in the 20. pump housing.
