The bit rate for the I
register. The value depends on the audio sample rate desired, and the data size and
format (stereo/mono) used. For example, a 48 kHz sample rate for 16-bit stereo data
requires a bit rate of 48,000×16×2 = 1.536 MHz.
The bit rate for the I
The value depends on the audio sample rate, as well as the data size and format used.
The calculation is the same as for I2SRXBITRATE.
The Transmit Mode Control register contains additional controls for transmit clock source,
enabling the 4-pin mode, and how MCLK is used. See
useful mode combinations.
MCLK. Eight bits of fractional divide supports a wide range of possibilities. A value of
MCLK. A value of 0 stops the clock. Eight bits of fractional divide supports a wide
MCLK rate denominator. This value is used to divide PCLK to produce the
MCLK rate numerator. This value is used to multiply PCLK by to produce the
