LM4F232H5QC data sheet - missing footnotes

Hi All

This has reference to the Analog Comparator section of the Data Sheet. Does anyone know how/where I can find the footnotes?

It mentions PF0(9), PF1(9), PF2(9) and I am unable to find the (9) footnote.

Thanks in advance

Regards

KLG

    The (9) is not a footnote.  (although the notation can lead to this belief)  Instead - the (9) indicates the particular multiplex selection for that MCU pin.  The numbers refer to the MCU pin-selection columns - starting from the left (1) and increasing to the right (15).   Here's an extract (from our MCU data sheet):

    To save space here - did not extend this chart down to PF0 - that row indeed shows the comparator selection w/in column labeled (9).  The GPIO section of your MCU datasheet differs slightly from ours - the use & explanation is just as I've described herein...  (nice verified answer tick gratefully received)

    *** Update - "use" as I've provided may not quite reach hallowed, "Good for Gov't Work" standard.  Your desired (9) bit encoding is automatically handled by your entry w/in StellarisWare's PinType() and PinConfigure() functions.  (you may review the encoding w/in the GPIOPCTL Register - and perhaps related others)

    Thanks for the quick responses. That was brilliant!

    Thank you - but "brilliant enough" for you to tick the "Verified Answer" box w/in your initial post?  You may consider same action for your PF0 issue - which earlier was also resolved...  (we are running "bit low" of threadbare T-Shirts offered for our service...)
