Clocking Control 2 (Address 05h)
SCLK Equals MCLK
Configures the SCLK signal source and speed for master mode.
MCLK Divide By 2
Configures a divide of the input MCLK prior to all internal circuitry.
MCLK Disable
Configures the MCLK signal prior to all internal circuitry.
Note:
Speed Mode
Configures the speed mode of the CODEC in slave mode and sets the appropriate MCLK divide ratio for
LRCK and SCLK in master mode.
Notes:
1. Slave/Master Mode is determined by the M/S bit in
2. Certain sample and MCLK frequencies require setting the SPEED[1:0] bits, the 32k_GROUP bit
