Serial Port (SPORT) Frame Synch Timing
Table 19 and Figure 22 describe SPORT frame synch operations.
To determine whether communication is possible between two devices at clock speed n, the following specifications must
be confirmed: 1) frame sync delay and frame sync setup and hold, 2) data delay and data setup and hold, and 3)
R/TCLK width.
