23.4.3
The following diagrams explain the timing relationship of all shift and sample processes in the
HSPI. Figure 23.3 shows the conditions when FBS = 0, figure 23.4 shows the conditions when
FBS = 0 (continuous transfer), figure 23.5 shows the conditions when FBS = 1, and figure 23.6
shows the conditions when FBS = 1 (continuous transfer). It can be seen that if CLKP in SPCR is
0, transmit data is shifted at the falling edge of HSPI_CLK and receive data is sampled at the
rising edge of HSPI_CLK. The opposite is true when CLKP = 1.
