Note:
Freescale Semiconductor
• All the timings for the SSI are given for a non-inverted serial clock polarity (TSCKP/RSCKP = 0) and a non-inverted frame sync
• All timings are on pads when SSI is being used for data transfer.
• ”Tx” and “Rx” refer, respectively, to the transmit and receive sections of the SSI.
• For internal frame sync operation using external clock, the FS timing is the same as that of Tx data (for example, during AC97
(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 figures.
