The timing diagram shown in Figure 41-11 shows an SPI data transfer between two devices using a character length of five bits with the SPICLK being symmetrical.
The timing diagram with SPICLK asymmetrical (Figure 41-8) shares similar characterizations with Figure 41-11 except that the data transfer is one SYSCLK cycle longer per bit during the low pulse (CLKPOLARITY = 0) or during the high pulse (CLKPOLARITY = 1) of the SPICLK.
Figure 41-11 is applicable for 8-bit SPI only and is not for C28x devices that are capable of working with 16-bit data. The figure is shown for illustrative purposes only.
