* **mode=0b00** sets straight Matrix Mode
* **mode=0b01** sets "FFT/DCT" mode and activates submodes
-When submode2 is 0, for FFT submode the following schedules may be selected:
+**FFT/DCT mode**
+
+submode2=0 is for FFT. For FFT submode the following schedules may be
+selected:
* **submode=0b00** selects the ``j`` offset of the innermost for-loop
of Tukey-Cooley
* **submode=0b00** selects the ``j`` offset of the innermost for-loop,
* **submode=0b01** selects the ``j+1`` offset of the innermost for-loop,
-in Matrix Mode, skip allows dimensions to be skipped from being included
+**Matrix Mode**
+
+In Matrix Mode, skip allows dimensions to be skipped from being included
in the resultant output index. this allows sequences to be repeated:
```0 0 0 1 1 1 2 2 2 ...``` or in the case of skip=0b11 this results in
modulo ```0 1 2 0 1 2 ...```
