This read-only field is reserved and always has the value zero.
I2S clock divider value
This field sets the divide value for when the fractional clock divider is used as the source for the I
master clock. The clock input to the fractional clock divider is set by the SOPT2[I2SSRC] bit.
Divider output clock = Divider input clock × [(I2SFRAC+1) / (I2SDIV+1) ]
NOTE: The I2S clock must be disabled (SCGC6[I2S] = 0) before altering this bitfield.
This read-only field is reserved and always has the value zero.
I2S clock divider fraction
This field sets the multiply value for when the fractional clock divider is used as a the source for I
master clock. The clock input to the fractional clock divider is set by the SOPT2[I2SSRC] bit.
Divider output clock = Divider input clock × [(I2SFRAC+1) / (I2SDIV+1) ]
NOTE: The I2S clock must be disabled (SCGC6[I2S] = 0) before altering this bitfield.
