DESCRIPTION
X
FLAG output value
1
Phone mode enable
0
Phone mode disable
X
Decimator FIR overflow flag (valid only during read cycle)
1
16-bit ADC mode
0
Not-16-bit ADC mode [(15+1)– bit mode]
X
0
Reserved (TLC320AD50C only)
0
FSD enable (TLC320AD52C only)
1
FSD disable (TLC320AD52C only)
1
Analog loopback enabled
0
Analog loopback disabled
Default value: 00000000
Writing 0s to the reserved bits is suggested.
6.3
Control Register 3
The following command contains the frame-sync delay (FSD) register address and loads D7 (MSB)–D0 into the FSD
register. The data byte (D5–D0) determines the number of SCLKs between FS and the delayed frame-sync signal,
FSD. The minimum data value for this portion of the register, bits D5–D0, is decimal 18.

DESCRIPTION
X
Number of SCLKs between FS and FSD
X
Binary number of slave devices (3 maximum for TLC320AC50C, 1 maximum for
TLC320AC52C)
Default value: 00000000
Writing 0s to the reserved bits is suggested.

Analog output gain = – 12 dB
0
1
Analog output gain = – 6 dB
0
Analog output gain = 0 dB
X
Sample frequency select (N): fs = MCLK/(128 N) or MCLK/(512 N)
1
Bypass internal DPLL
0
Enable internal DPLL
Default value: 00000000
The value of the sample frequency divisor, N, is determined by the octal representation of bits D4–D6. Hence,
001 = 1, 010 = 2, etc. By setting D4–D6 to 000, N = 8 is selected.
