-* **offs** (4 bits) - unsigned offset
+* **offs** (3 bits) - unsigned offset
 * **yx** (1 bit) - swap XY to YX
+* **inv** (1 bit) inverts X if yx=0, Y if yx=1
 * **SVd** dimension size
 * **rmm** REMAP mask
 * **mm** mask mode
-* **sk** skip
+* **sk** (1 bit) skips 1st dimension if set

+Dimensions are calculated exactly as `svindex`. `rmm` and
+`mm` are as per `svindex`.
