Serial Ports
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) SCLK width.
Serial port signals (SCLK, FS, DxA,/DxB) are routed to the
DAI_P20–1 pins using the SRU. Therefore, the timing specifica-
tions provided below are valid at the DAI_P20–1 pins.
