ECSPI Slave Mode Timing

Figure 31 depicts the timing of ECSPI in slave mode. Table 44 lists the ECSPI slave mode timing

characteristics.

4.7.3

Enhanced Serial Audio Interface (ESAI) Timing Parameters

The ESAI consists of independent transmitter and receiver sections, each section with its own clock

generator. Table 45 shows the interface timing values. The number field in the table refers to timing signals

found in Figure 32 and Figure 33.
