Freescale Semiconductor
SRXD Setup time before STCK low - Slave
SRXD Hold time after STCK low - Slave
Operating Conditions: V
1. Slave mode is externally generated clocks and frame syncs
2. Max clock frequency is IP_clk/4 = 40MHz / 4 = 10MHz for an 80MHz part.
3. All the timings for the SSI are given for a non-inverted serial clock polarity (TSCKP=0 in SCR2 and RSCKP=0 in SCSR)
and a non-inverted frame sync (TFSI=0 in SCR2 and RFSI=0 in SCSR). If the polarity of the clock and/or the frame sync
have been inverted, all the timings remain valid by inverting the clock signal STCK/SRCK and/or the frame sync STFS/SRFS
in the tables and in the figures.
