CLOCK CONTROL REGISTER (0x00)
The clocks and data rates are automatically determined by the TAS5711. The clock control register contains the
auto-detected clock status. Bits D7–D5 reflect the sample rate. Bits D4–D2 reflect the MCLK frequency. The
device accepts a 64 fS or 32 fS SCLK rate for all MCLK ratios, but accepts a 48 fS SCLK rate for MCLK ratios of
192 fS and 384 fS only.
