t is axi_clk cycle time. The maximum allowed axi_clk frequency is 133 MHz, whereas the maximum allowed BCLK frequency
is 104 MHz. As a result if BCD = 0, axi_clk must be
BCLK of 66.5 MHz. When the clock branch to WEIM is decreased to 104 MHz, other busses are impacted which are clocked
from this source. See the CCM chapter of the i.MX51 Multimedia Applications Processor Reference Manual (MCIMX51RM)
for a detailed clock tree description.
BCLK parameters are being measured from the 50% point that is, high is defined as 50% of signal value and low is defined
as 50% as signal value.
For signal measurements “High” is defined as 80% of signal value and “Low” is defined as 20% of signal value.
The lower 16 bits of the WEIM bus are limited to 90 MHz.”
