User manual
5.2.5 SPI format with CPOL = 1,CPHA = 1
5.3 Semiconductor Microwire frame format
The transfer signal sequence for SPI format with CPOL = 1, CPHA = 1 is shown in
Figure
In this configuration, during idle periods:
If the SSP is enabled and there is valid data within the transmit FIFO, the start of
transmission is signified by the SSEL master signal being driven LOW. Master’s MOSI is
enabled. After a further one half SCK period, both master and slave data are enabled onto
their respective transmission lines. At the same time, the SCK is enabled with a falling
edge transition. Data is then captured on the rising edges and propagated on the falling
edges of the SCK signal.
After all bits have been transferred, in the case of a single word transmission, the SSEL
line is returned to its idle HIGH state one SCK period after the last bit has been captured.
For continuous back-to-back transmissions, the SSEL pins remains in its active LOW
state, until the final bit of the last word has been captured, and then returns to its idle state
as described above. In general, for continuous back-to-back transfers the SSEL pin is
held LOW between successive data words and termination is the same as that of the
single word transfer.
Figure 20–101
shows the same format when back-to-back frames are transmitted.
