This register allows the calculation of the incoming sample rate by the host microcontroller from the equation
ORR=Fso/Fsi. The Fso is determined by OMCK, whose frequency is assumed to be 256*Fso. ORR is rep-
resented as an unsigned 2-bit integer and a 6-bit fractional part. The value is meaningful only after the PLL
has reached lock. For example, if the OMCK is 12.288 MHz, Fso would be 48 kHz (48 kHz =
12.288 MHz/256). Then, if the input sample rate is also 48 kHz, you would get 1.0 from the ORR register
(The value from the ORR register is hexadecimal, so the actual value you will get is 40h).
If F
small amount of jitter on either clock can cause the LSB ORR[0] to oscillate.
ORR[7:6] - Integer part of the ratio (Integer value=Integer(SRR[7:6])).
ORR[5:0] - Fractional part of the ratio (Fraction value=Integer(SRR[5:0])/64).
ID[3:0] - ID code for the CS8416. Permanently set to 0010
VER[3:0] = 0001 (revision A)
VER[3:0] = 0010 (revision B)
VER[3:0] = 0011 (revision C)
VER[3:0 ] = 0111 (revision D)
VER[3:0] = 1111 (revision E)
