92 / 152 page i.MX27 and i.MX27L Data Sheet, Rev. 1.7 92 Freescale Semiconductor Electrical Characteristics 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 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. 4.3.12 Wireless External Interface Module (WEIM) All WEIM output control signals may be asserted and deasserted by internal clock related to BCLK rising edge or falling edge according to corresponding assertion/negation control fields. Address always begins related to BCLK falling edge but may be ended both on rising and falling edge in muxed mode according to control register configuration. Output data begins related to BCLK rising edge except in muxed mode where both rising and falling edge may be used according to control register configuration. Input data, ECB and DTACK all captured according to BCLK rising edge time. Figure 53 shows the timing of the WEIM module, and Table 50 lists the timing parameters. |
