SSI Receiver Timing with External Clock
Figure 52
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 STCK/SRCK and/or the frame
sync STFS/SRFS shown in the tables and in the figures.
All timings are on AUDMUX pads when the SSI is being used for data
transfer.
“Tx” and “Rx” refer to the Transmit and Receive sections of the SSI.
For internal Frame Sync operation using external clock, the FS timing will
be same as that of Tx Data, for example, during the AC97 mode of
operation.
