3.2.2.1.2 Margining Subpage

The 

Margining

 subpage is shown in 

Figure 3-6

. This subpage provides the settings for the margin-low, margin-

high, and nominal DAC outputs. Self-resetting triggers are used to trigger the margin-high and margin-low 
voltage levels for each DAC channel. The 

Code Step

 and 

Slew Rate

 drop-down menu settings are also provided 

on this page to control the slew of each margin high or low trigger (

Trigger MHx

). The register settings can be 

programmed or retrieved using the 

Program NVM

 or 

Reload NVM

 checkboxes, respectively.
