Note that the immediate (`SVi`) spans 7 bits (16 to 22)
-`ms` - bit 23 - allows for setting of MVL. `vs` - bit 24 - allows for
-setting of VL. `vf` - bit 23 - sets "Vertical First Mode" which is
-stored in `MSR` bit 6 (**TODO: needs approval**)
+* `ms` - bit 23 - allows for setting of MVL.
+* `vs` - bit 24 - allows for setting of VL.
+* `vf` - bit 23 - sets "Vertical First Mode".
Note that in immediate setting mode VL and MVL start from **one**
i.e. that an immediate value of zero will result in VL/MVL being set to 1.
