Legal values for ALIGN_COMMA_WORD of GTPE2_CHANNEL?

Within 7 Series FPGAs Transceivers Wizard(3.2), I select "Align to four byte boundaries" for "RX comma detection", that means ALIGN_COMMA_WORD is set to 4.

But during the simulation, the Tcl console complains that ALIGN_COMMA_WORD should only be from 1 to 2, and ug482  also doesn't give a value other than 1 or 2 for ALIGN_COMMA_WORD.

 

So at last legal values for ALIGN_COMMA_WORD are only 1 to 2?

Why illegal for 4?
