Figure 8. GUI GPO Configuration Window
•
Active Low (Polarity) —specifies GPO pin polarity
•
Sequence After Shutdown —UCD9081 ENx and GPOs output can be marked to resequence the
system (as defined by the current sequencer configuration) if they are specified as a dependency in
the DependencyMasks register.
•
Store to Buffer and Close Buttons —The Store to Buffer button saves the current window entries to a
GUI buffer, and the Close button closes the window without saving the form entries.
Sequencing conditions for a GPO:
•
None —GPO is not sequenced
•
Time —number of milliseconds before this GPO is enabled
•
Parent (Reg) —number of milliseconds to delay after the parent rail achieves regulation before
enabling this GPO
•
Parent (V) —voltage at which the parent rail must be before this GPO is enabled
Specific user data can be stored within the UCD9081 device by entering the text in the User Data window
