The transition of shift and latch edge of SSPCLK is programmable. This figure uses the
falling edge as shift edge (drawn bold).
The bit timing is repeated for all bits to be transmitted or received.
The active level of the chip enable lines is programmable. This figure uses an active low
CE (drawn bold). At the end of a transmission or reception the CE signal is disabled in sin-
gle transfer mode. In continuous transfer mode it remains active.
