PC FUNCTION GNERATOR K8016 Description of operation The shift registers IC2, IC3, IC19 and IC21 store the setup data controlling the operations of the generator. The 32-bit data word to these registers is fed in serial mode via optocoupler IC37 from the printer port connector J7. The clock to the shift registers is fed via optocoupler IC20 and the PAL circuit IC22. Before transferring the data the optocoupler input supply voltage must be turned on by pulling pin 17 of connector J7 down. The supply voltage to the optocouplers is fed from the printer port data lines via 8 diodes and transistor T8. Signals C0 and C1 connected from optocouplers IC35 and IC36 to IC22 are used to control the function of the outputs of IC22. The status of this pins is valid (and shifted to the output pins 14 and 15 of IC22) after the CLK rising edge to pin 1 of IC22. C0 C1 Operation mode 0 0 Run mode 1 0 RCK2 goes high at the rising edge of the CLK to pin 1 of IC22. Data will be latched to the shift register IC5. 0 1 RCK1 goes high at the rising edge of the CLK to pin 1 of IC22. Data will be latched to the shift registers IC2 ...
