CLOCK CONTROL REGISTER (0x00)
In the manual mode, the clock control register provides a way for the system microprocessor to update the data
and clock rates based on the sample rate and associated clock frequencies. In the autodetect mode, the clocks
are automatically determined by the TAS5705. In this case, the clock control register contains the autodetected
FS and MCLK status as automatically detected (D7–D2). Bits D7–D5 select the sample rate. Bits D4–D2 select
the MCLK frequency. Bit D0 is used in manual mode only. In this mode, when the clocks are updated a 1 must
be written to D0 to inform the DAP that the written clocks are valid.
