0
Normal operation with FIR filter
1
Enable HYBRID transmitter/MIC amps (A3,A4)
0
Disable HYBRID transmitter/MIC amps (A3,A4)
1
16-bit data format for DAC
0
15-bit data + LSB format for DAC
Default value: 00000000
NOTE: A software reset is a one-shot operation and this bit is cleared to 0 after reset. It is not necessary to write a 0 to end the
master reset operation.

Frequency Divider N = 1
0
Frequency Divider N = 32
Default value: 00000000
NOTE: The serial port interface always gluelessly works with the DSP. The following modes will not produce
50% duty cycle SCLK:
1. If the number of devices in cascade >4 and N is an odd number (i.e., N = 1, 3, 5,...)
2. If the number of devices in cascade
≤4, FIR is bypassed, and N ≠ 4, 8, 12, 16, 20, 24, 28, 32
