Figure 34. DAC8812 Equivalent Logic Interface
Two additional pins, RS and MSB, provide hardware control over the preset function and DAC register loading. If
these functions are not needed, the RS pin can be tied to logic high. The asynchronous input RS pin forces all
input and DAC registers to either the zero-code state (MSB = 0), or the half-scale state (MSB = 1).
