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).
