All DAP coefficients are 3.23 format unless specified otherwise.
Registers 0x3B through 0x46 should be altered only during the initialization phase.
CLOCK CONTROL REGISTER (0x00)
The clocks and data rates are automatically determined by the TAS5713. The clock control register contains the
autodetected clock status. Bits D7–D5 reflect the sample rate. Bits D4–D2 reflect the MCLK frequency.
