I/O Registers
This read/write bit controls the timing relationship between the serial clock and SPI data. (See
Figure 13-4
and
Figure
13-6.) To transmit data between SPI modules, the SPI modules must have
identical CPHA values. When CPHA = 0, the SS pin of the slave SPI module must be set to logic 1
between bytes. (See
Figure
13-12.) Reset sets the CPHA bit.
