The values for I2SCLL and I2SCLH should not necessarily be the same. Software can set
different duty cycles on SCL by setting these two registers. For example, the I
specification defines the SCL low time and high time at different values for a 400 kHz I
rate. The value of the register must ensure that the data rate is in the I
of 0 through 400 kHz. Each register value must be greater than or equal to 4.
