Table 26Table 26 shows the control registers for the auto slice modes.
Figure 12: DAC Slice Mode Waveform
The average mode generates a threshold value automatically. This generated threshold is used to compare to the output of the slice
circuit to re-create the digital data. The slice circuit uses an external capacitor to generate a charge time constant that is equal to
charging to 95 percent of a bit level in two bit time periods. The data protocol should add a header to the data to allow the slice circuit to
determine the average level. Refer to AMIS application note “Setting Up the Data Slicing Modes” for more information. Figure 13 shows
a typical waveform for the average mode. Table 26 shows the control registers for the auto slice modes.
