Functional Mode (Address 03h)
DAC Functional Mode (DAC_FM[1:0])
Default = 11
Master Mode
00 - Single-Speed Mode (4 to 50 kHz sample rates)
01 - Double-Speed Mode (50 to 100 kHz sample rates)
10 - Quad-Speed Mode (100 to 200 kHz sample rates)
Slave Mode
11 - (Auto-detect sample rates)
Function:
Selects the required range of sample rates for the DAC serial port.
ADC Functional Mode (ADC_FM[1:0])
Default = 11
Master Mode
00 - Single-Speed Mode (4 to 50 kHz sample rates)
01 - Double-Speed Mode (50 to 100 kHz sample rates)
10 - Quad-Speed Mode (100 to 200 kHz sample rates)
Slave Mode
11 - (Auto-detect sample rates)
Function:
Selects the required range of sample rates for the ADC serial port.
MCLK Frequency (MFREQ[2:0])
Default = 000
Function:
Sets the appropriate frequency for the supplied MCLK. For TDM and OLM #2 operation, ADC/DAC_SCLK
must equal 256Fs. For OLM #1 operation, ADC/DAC_SCLK must equal 128Fs. MCLK can be equal to or
greater than the higher frequency of ADC_SCLK or DAC_SCLK.
