NOTES
1.
Execute consecutive memory write instructions while manipulating the data between WRITEs so that each
WRITE presents the next bit.
The serial data loading is triggered by the CLK pulse which is asserted by a decoded memory WRITE to
memory location 2000, R/W, and 02. A WRITE to address 4000 transfers data from input shift register to DAC
register.

2.
Clock generated by WR and decoding address 8000.
Data is clocked in 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.
Serial data must be present in the right justified format in registers H & L of the microprocessor.
