TMS320F280049: pin 31 of 100 pin version

Part Number:TMS320F280049

Hi,

in datasheet page 17,

pin 31 is described as C3, CMP4_HP1, CMP4_HN1, CMP4_LP1, COMP4_LN1, AIO245.

in datasheet page 18,

pin 31 is describes as PGA4_IN, CMP4_HP2, CMP4_LP2.

And in page 98 we have the table below.

My understanding is: pin 31 is both ADC-C3 input, AIO245, and PGA4_IN, these 3 functions take effect at the same time without muxing, right?

And if I choose HPMXSEL=1, CMP4_HP will be connected to CMP4_HP1, which is pin 31,

if I choose HPMXSEL=2, CMP4_HP will be connected to CMP4_HP2, which is still pin 31, right?

And if I choose HPMXSEL=2 and HNMXSEL=1, both CMP4_HP and CMP4_HN will be connected to pin 31, right?
