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 determined automatically by the TAS5086. In this case, the clock control register contains the autodetected
clock status as automatically detected. Bits D7–D5 select the sample rate. Bits D4–D2 select the MCLK
frequency. Bit D1 selects the bit clock (SCLK) frequency. Bit D0 is used in manual mode only. In this mode,
when the clocks are updated, a 1 must be written to D1 to inform the TAS5086 that the written clocks are valid.
