SFSST: Incoming Biphase Signal, Sampling Frequency Calculate Status
0: SFSOUT[3:0] Output is calculated
1: In the process of calculating or unlocked
SCSBIT1: Detected Channel Status Bit1 Flag
0: CS Bit1 = 0 (Audio data)
1: CS Bit1 = 1 (Non-audio data)
SFSOUT[3:0]: Incoming Biphase Signal, Actual Sampling Frequency
0000: Out of range
0001: 8 kHz
0010: 11.025 kHz
0011: 12 kHz
0100: 16 kHz
0101: 22.05 kHz
0110: 24 kHz
0111: 32 kHz
1000: 44.1 kHz
1001: 48 kHz
1010: 64 kHz
1011: 88.2 kHz
1100: 96 kHz
1101: 128 kHz
1110: 176.4 kHz
1111: 192 kHz
NOTE
When SFSST becomes '1' (that is, in the process of calculating or unlocked), SFSOUT
holds the previous data. SFSST and SFSOUT always output the status when these
registers are read. The other registers do not have clear functions when these are read.
To enable these registers, DIR must be powered on (Register 40h/RXDIS = 0).
