STPMIC25APQR Audit
Assign a Terminal Order from 1 to 10, starting with Power. Power should be Terminal Order 1, and Ground should be last, Terminal Order 10. For Orientation, set Power to "Top" and Ground to "Bottom." For the remaining sections/groups, you may decide the Terminal Order and Orientation yourself. For Orientation, distribute them between "Left" and "Right" — don't put everything on one side. Each group/section should have a different orientation.
Thought for 9 sec
I’ll assign group-level Terminal Order with Power as 1 and Ground as 10, set Power Top/Ground Bottom, and split the remaining groups across Left/Right as evenly as possible despite only four orientation values being available.
Worked for 1 min 18 sec
Done — I assigned Terminal Order and Orientation to all pins and verified the updates.
Open items:
- There are only four Orientation values (
Top,Bottom,Left,Right) but six groups, so unique orientation per group is not physically possible. I used: Power=Top, Ground=Bottom, Buck/I2C=Left, LDO/Control=Right.
Applied order:
Power: 1Buck: 2LDO: 3I2C: 4Control: 5Ground: 10
