SPI 1 Master Using DATA_READY Level Trigger
Figure 19-29 shows the timing diagram for the SPI 1 master using the DATA_READY level trigger. The
signal values and units of measure for Figure 19-27 through Figure 19-32 are found in Table 19-17 on
page 19-34. Detailed information about the operation of individual signals can be found in Chapter 13,
“Serial Peripheral Interface 1 and 2.”
signal values and units of measure for Figure 19-27 through Figure 19-32 are found in Table 19-17 on
page 19-34. Detailed information about the operation of individual signals can be found in Chapter 13,
“Serial Peripheral Interface 1 and 2.”
