CLOCK CONTROL REGISTER (0x00)
The clocks and data rates are automatically determined by the TAS5707. 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-f
S
or 32-f
S
SCLK rate for all MCLK rates, but accepts a 48-f
S
SCLK rate for MCLK rates of
192 f
S
and 384 f
S
only.
