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, PCM1870
generates LRCK and BCK from the system clock. In slave mode, it receives LRCK and BCK from another
device.
MSTR = 0
MSTR = 1
Slave interface (default)
Master interface
BIT0: Bit Length Selection for Audio Interface
Default value: 1
This bit is used to select data bit length for the ADC output.
BIT0 = 0
BIT0 = 1
Reserved
16 bits (default)
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 resets to 0 automatically.
SRST = 0
SRST = 1
Reset disabled (default)
Reset enabled
NPR[5:0]: System Clock Rate Selection
Default value: 00 0000
These bits are used to select the system clock rate. See
Table 8
for details.
MBST: BCK Output Configuration in Master Mode
Default value: 0
This bit is used to control the BCK output configuration in master mode. V
IO
(I/O cell power supply) power
consumption can be reduced by adjusting BCK edge to bit number when setting MBST = 1. This is effective in
master mode (register 69 MSTR = 1).
MBST = 0
MBST = 1
Normal Output (default)
Burst output
