2-Wire Interface (Pulse Mode, Figure 5) In 2-wire pulse mode,alogic HIGH at U P/DN programsthe DAC register to increment and each rising edge at CLK increments the upper six bits of the register by one count. Similarly, a logic LOW at UP/DN set the DAC register to decrement and a rising edge at CLK decrements the upper six bits of the register by one count. Each count in 2-wire mode changes the DAC output by a single four LSB step. The DAC register stops incramenting at 11111100B and stops decrementing at OOOOOOOOB and will not roll overin 2-wire pulse mode. The last two LSBs are always zero in pulse mode.
