Table 539: Interrupt Request Control register (I2SIRQ - address 0xE008 801C) bit description
The bit rate for the I
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.
Table 540: Transmit Clock Rate register (I2TXRATE - address 0xE008 8020) bit description
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 I2STXRATE.

When the FIFO is empty, the transmit channel will repeat transmitting the same data
until new data is written to the FIFO.
When mute is true, the data value 0 is transmitted.
When mono is false, two successive data words are respectively left and right data.
