The Sample Rate Ratio is Fso divided by Fsi. This value is represented as an integer and a fractional
part. The value is meaningful only after the both the PLL and SRC have reached lock, and the SRC
output is being used
SRR7-6The integer part of the sample rate ratio
SRR5-0 The fractional part of the sample rate ratio
Either channel status data buffer E or user data buffer E (provided UBM bits are set to block mode)
is accessible via these register addresses.
