6.13 Serial Peripheral Interface (SPI) Timing
This section contains both Master Mode and Slave Mode timing data.
6.13.1 Master Mode Timing
Table 6-32 lists the master mode timing (clock phase = 0) and Table 6-33 lists the timing (clock
phase = 1). Figure 6-18 and Figure 6-19 show the timing waveforms.
