Figure 30 SSP read timing

1 The transition of shift and latch edge of SSPCLK is programmable. This figure uses the

falling edge as shift edge (drawn bold).

2 The bit timing is repeated for all bits to be transmitted or received.

3 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.
