NOTES:
1.
Clock generated by WR and decoding address 8000
2.
Data is clocked into the DAC shift register by executing memory write instructions. the clock input is
generated by decoding address 8000 and WR. Data is then loaded into the DAC register with a memory
write instruction to address 4000.
3.
Serial data must be present in the right justified format in registers H & L of the microprocessor.
