    Figure 7. MMD (ATI) Drives Clock, MMD Write BMI Timing
    (MMD_MODE_SEL=1, MASTER_MODE_SEL=0, MMD_CLKOUT=0)
    Note:
    All timings assume that the hclk is running at 133 MHz.
    Note:
    At this mode, the maximum frequency of the BMI_CLK/CS can be up to 36 MHz (doubles as maximum data pad speed).
    3.8.1.2
    BMI Drives the BMI_CLK/CS
    In this mode MMD_MODE_SEL and MMD_CLKOUT are both set. The software must know which
    mode it is now (READ or WRITE). When the BMI_WRITE is high, BMI drives BMI_CLK/CS out if the
    TxFIFO is not emptied. When BMI_WRITE is low, user can write a 1 to READ bit of control register1 to
    issue a write cycle (MMD write BMI).
    3.8.1.3
    MMD Read BMI Timing
    Figure 13 shows the MMD read BMI timing when BMI drives the BMI_CLK/CS. When the BMI_WRITE
    is high, the BMI drives BMI_CLK/CS out if data is written to TxFIFO (BMI_READ_REQ become high),
    BMI puts data into data bus and enable data out on the rising edge of BMI_CLK/CS. The MMD devices
    can latch the data on each falling edge of BMI_CLK/CS.
    It is recommended that the MMD do not change the BMI_WRITE signal from high to low when the
    BMI_READ_REQ is asserted. If user writes data to the TxFIFO when the BMI_WRITE is low, the BMI
    will drive BMI_CLK/CS out once the BMI_WRITE is changed from low to high.
