MSTR: Master or Slave Selection for Audio Interface
Default value: 0
This bit is used to select either master or slave mode for the audio interface. In master mode, the PCM3793/94
generates LRCK and BCK from the system clock. In slave mode, it receives LRCK and BCK from another
device.
BIT0: Bit Length Selection for Audio Interface
Default value: 1
This bit is used to select the data bit length for DAC input.
SRST: System Reset
Default value: 0
This bit is used to enable system reset. All circuits are reset by setting SRST = 1. After completing the reset
sequence, SRST is set to 0 automatically.
NPR[5:0]: System Clock Rate Selection
Default value: 000000
MSR[2:0]: System Clock Dividing Rate Selection in Master Mode (Register 70)
Default value: 000
These bits are used to select the system clock rate and the dividing rate of the input system clock. See
for the details.
