Register Functional Summary
There are seven control registers that are used as follows:
Register 0 The No-Op register. Addressing register 0 allows secondary communications requests without altering
any other register.
Register 1 Control register 1. The data in this register controls:
Software reset
Software power down
Normal or auxiliary analog inputs enabling
Normal or auxiliary analog inputs monitoring
Selection of monitor amplifier output gain
Selection of digital loopback
Selection of16-bit or (15+1)-bit mode of DAC operation
Register 2 Control register 2. The data in this register:
Contains the output value of FLAG
Selects phone mode
Contains the output flag indicating a decimator FIR filter overflow
Selects either 16-bit mode or (15+1)-bit mode of ADC operation
Enables analog loopback
Register 3 Control register 3. The data in this register:
Sets the number of SCLK delays between FS and FSD
Informs the master device of how many slaves are connected in the chain
Register 4 Control register 4. The data in this register:
Selects the amplifier gain for the input and output amplifiers
Sets the sample rate by choosing the value of
N from 1 to 8 where fs = MCLK/(128 N) or
MCLK/(512
N)
Selects the PLL. If the PLL is selected, the sampling rate is set to MCLK/(128
N). If the PLL is
bypassed, the sampling rate can be set to MCLK/(512
N).
Register 5 Reserved for factory test. Do not write to this register.
Register 6 Reserved for factory test. Do not write to this register.
