11.5 SEI Transfer Formats

11.5 SEI Transfer Formats
The transfer formats are set using CPHA and CPOL (SECR<CPHA,CPOL>). CPHA allows transfer protocols to
be selected between two.
11.5.1 CPHA (SECR register bit 2) = 0 format
Figure 11-2 shows a transfer format where CPHA = 0.
Figure 11-2 Transfer Format where CPHA = 0
In master mode, transfer is initiated by writing new data to the SEDR register. At this time, the new
data changes state on the MOSI pin a half clock period before the shift clock starts pulsing. Use BOS
(SECR<BOS>) to select whether the data should be shifted out beginning with the MSB or LSB. The
SEF flag (SESR<SEF>) is set after the last shift cycle.
In slave mode, writing data to the SEDR register is inhibited when the SS pin is “L”. A write during
this period causes collision of writes, so that the WCOL flag (SESR<WCOL>) is set.
Therefore, when writing data to the SEDR (SEI Data Register) after the SEF flag is set upon comple-
tion of transfer, make sure the SS pin goes “H” again before writing the next data to the SEDR register.
Note:In slave mode, be careful not to write data while the SEF flag is set and the SS pin remains “L”.
11.5.2 CPHA = 1 format
Figure 11-3 shows a transfer format where CPHA = 1.
