The following 10 registers contain the decoded Q-channel subcode data
8.17
This register allows the calculation of the incoming sample rate by the host microcontroller from the equation
SRR=Fso/Fsi. The Fso is determined by OMCK. This value is represented as an integer and a fractional part. The
value is meaningful only after the both the PLL has reached lock. F
would be 48KHz(48KHz=12.288MHz/256). Then if the in put sample rate is also 48KHz, you would get
1.0 from the SRR register.(The value from the SRR register is hexadecimal, so the actual value you will
get is 40h)
8.18
Either channel status data buffer E or user data buffer E is accessible through these register addresses.
