Specifications
Note: All the timings assume that the hclk is running at 133 MHz.
Note: The MIN period of the 1T is assumed that MMD latch data at falling edge.
Note: If the MMD latch data at next rising edge, the ideally max clock can be as much as double, but because the BMI data pads
are slow pads and it max frequency can only up to 18MHz, the max clock frequency can only up to 36 MHz.

Figure 7
CS BMI checks the BMI_WRITE logic level to determine if the current cycle is a write cycle. If the BMI_
WRITE is logic low, it latches data into the RxFIFO on each falling edge of BMI_CLK/CS signal.
