Figure 490 shows the sequence of Modulation Words within a Modulation Cycle if LOOP
function is used. Note that an alternate modulated waveform is generated using only two
Modulation Words, in this case Modulation Word 0 and Modulation Word 1.

Banked mode
Figure 491 describes the interconnection of four channels controlling two injector banks.
Note that two output pins are not connected since the boost control is shared between
channels [0] and [1] and channels [2] and [3].
