6.7 12-bit Parallel DAC Interface
The interface between the MC2840 chip set and 2 quad 12 bit DAC’S is shown in the following
figure.
Comments on Schematic
The 12 data bits are written to the DAC addressed by address bits A0 and A1 in Quad DAC 1, when
A2 is 0. The 12 data bits are written to the DAC addressed by address bits A0 and A1 in quad DAC
2, when A2 is 1. In this fashion CP addresses 4000,4002,4004,and 4006 are used for axis 1-4, phase
A, and 4001,4003, 4005, and 4007, are used for axis 1-4 phase B.
