Table 726. I2S clocking and power control
The I2S bus provides a standard communication interface for digital audio applications.
The I2S bus specification defines a 3-wire serial bus, having one data, one clock, and one
word select signal. The basic I2S connection has one master, which is always the master,
and one slave. The I2S interface provides a separate transmit and receive channel, each
of which can operate as either a master or a slave.
Clock to the I2S0 and I2S1 register
interface and I2S0/1 peripheral clock.

The I2S0 is reset by the I2S0_RST (reset # 52).
The I2S1 is reset by the I2S1_RST (reset # 53).
The I2S0 interrupt is connected to slot # 28 in the NVIC.
The I2S1 interrupt is connected to slot # 29 in the NVIC.
For connecting the I2S receive and transmit lines to the GPDMA, use the DMAMUX
register in the CREG block (see

timer and SCT inputs.
The I2S input can operate in both master and slave mode.
The I2S output can operate in both master and slave mode, independent of the I2S
input.
Capable of handling 8-bit, 16-bit, and 32-bit word sizes.
Mono and stereo audio data supported.
Versatile clocking includes independent transmit and receive fractional rate
generators, and an ability to use a single clock input or output for a 4-wire mode.
