NOTE
• All the timings for the SSI are given for a non-inverted serial clock
polarity (TSCKP/RSCKP = 0) and a non-inverted frame sync
(TFSI/RFSI = 0). If the polarity of the clock and/or the frame sync have
been inverted, all the timing remains valid by inverting the clock signal
AUDx_TXC/AUDx_RXC and/or the frame sync
AUDx_TXFS/AUDx_RXFS shown in the tables and in the figures.
• All timings are on Audiomux Pads when SSI is being used for data
transfer.
• AUDx_TXC and AUDx_RXC refer to the Transmit and Receive
sections of the SSI.
• The terms, WL and BL, refer to Word Length (WL) and Bit Length(BL).
• For internal Frame Sync operation using external clock, the frame sync
timing is same as that of transmit data (for example, during AC97 mode
of operation).
