TPS65986: Object Position value in Alternate Mode Entry Sequence register

Part Number: TPS65986


I have a question about the Alternate Mode Entry Sequence register.  

I think there is some incorrect labeling of fields in the App Customization Tool...   In register 0x38, there is an 8-bit field called "Mode Number", which I originally confused to be the same as "Mode Value" in the Alternate Mode Configuration register.  However, I believe the TRM labels this as "Object Position", or "Mode Position".  

 

What exactly is the purpose and function of this 8-bit "Object Position" field?    It is currently set to 0xff, and things seem to be working, but I assume that is because I'm testing against things with only 1 alternate mode at the moment.

    Hi Eric,

    By default, the "Mode Number" for Alternate Mode Entry Queue Record #1 is set to 0x1. This "Mode Number" Value should let you select which mode of the alternate mode you enter. If you are only using 1 alternate mode, there is no need to put anything in this register. You could just put all 0's and see the same behavior.

    Thank you,

    Eric
