7.2.1 Two cyclic channels only (default - compression off)
This data format provides two cyclic data channels with no non-cyclic data. The total
data length is four words in and four words out.
To select this data format, set Pr MM.05 = 4. This data format is selected by default.

7.2.2 Three cyclic channels with Mode 1 non-cyclic data (compression off)
This data format provides three cyclic data channels, plus an additional channel for
Mode 1 (CT Single Word) non-cyclic data (See section 8.6 Mode 1 - CT Single Word
mode ). The total data length is eight words in and eight words out.
To select this data format, set Pr MM.05 = 106.
