reduce the wake-up time from the Standby mode. To
enter Standby mode, simply hold SCLK high after
DRDY/DOUT goes low; see Figure 37. Standby mode
can be initiated at any time during readback; it is not
necessary to retrieve all 24 bits of data beforehand.

Values given for fCLK = 4.9152MHz. For different fCLK frequencies, scale proportional to CLK period. Expect a ±3% variation when an
internal oscillator is used.
