Hi there
According to TI slva845a.pdf, margining function can be enable through two GPI (see figure 12)
Q1: what is difference between input source for margin enable and input source for margin low / not high? Both function can be used to select margin high or low? Why two GPI pins?
Q2: Margin enable is active high or low?
Q3: Once margin is enabled, how can I choose which power rail I want to margin?
Q4: Can I see real-time status in GPIO-monitor window in Fusion Digital power designer tool by connecting TI HPA172 to my CD90320 via PMbus interface?
Thanks
