CLOCK CONTROL REGISTER (0x00)
DEVICE ID REGISTER (0x01)
SLOS606D – MARCH 2009 – REVISED SEPTEMBER 2009............................................................................................................................................. www.ti.com
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 auto-detect mode, the clocks
are automatically determined by the TAS5706A. In this case, the clock control register contains the auto-detected
clock status as automatically detected (D7–D2). Bits D7–D5 selects 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.
