Figures 5.14 and 5.15 show the receive operation with normal framing and
alternate framing, respectively, in the unframed mode. There is a single
the frame sync signal that occurs only at the start of the first word, either
one SCLK before the first bit (normal) or at the same time as the first bit
(alternate). This mode is appropriate for multiword bursts (continuous
reception).
