mi0-2 and mo0-1 each select SVSHAPE0-3 to apply to a given register.
mi0-2 apply to RA, RB, RC respectively, as input registers, and
-likewise mo0-1 apply to output registers (FRT, FRS respectively).
-SVme is 5 bits, and indicates indicate whether the
+likewise mo0-1 apply to output registers (RT/FRT, RS/FRS) respectively.
+SVme is 5 bits (one for each of mi0-2/mo0-1) and indicates whether the
SVSHAPE is actively applied or not.
* bit 0 of SVme indicates if mi0 is applied to RA / FRA
* bit 1 of SVme indicates if mi1 is applied to RB / FRB
* bit 2 of SVme indicates if mi2 is applied to RC / FRC
* bit 3 of SVme indicates if mo0 is applied to RT / FRT
-* bit 4 of SVme indicates if mo1 is applied to Effective Address / FRS
+* bit 4 of SVme indicates if mo1 is applied to Effective Address / FRS / RS
(LD/ST-with-update has an implicit 2nd write register, RA)
