Freescale Semiconductor
“High” is defined as 80% of signal value, and “low” is defined as 20% of signal value.
BCLK parameters are measured from the 50% point. For example, “high” is defined as 50% of signal value and “low” is defined
as 50% of signal value.
Parameters W18, W20, W22, and W24 are tested when FCE=1. i.MX35 does not support FCE=0.
