Each channel has an element number register and a frame number register
(see Figure 89, Table 71, and Table 72). Load DMACFN with the number of
frames you want in each block. Load DMACEN with the number of elements
you want in each frame. You must have at least one frame and one element,
and you can have as many as 65535 of each:
1 ≤ frame number ≤ 65535
1 ≤ element number ≤ 65535
DMACEN and DMACFN are uninitialized after a DSP subsystem reset.
