6.14 Serial Peripheral Interface (SPI) Timing
This section contains both Master Mode and Slave Mode timing data.
6.14.1 Master Mode Timing
Table 6-31 lists the master mode timing (clock phase = 0) and Table 6-32 lists the timing (clock
phase = 1). Figure 6-17 and Figure 6-18 show the timing waveforms.
