Initialization/application information
2. Set all control bits for configuring the I²S (see the following table ).
3. Enable appropriate interrupts/DMA requests through IER.
4. Set the CR[I2SEN] bit to enable the I²S.
5. In AC97 mode, set the ACNT[AC97EN] bit after programming the ATAG register
(if needed, for AC97 Fixed mode).
6. In AC97 fixed mode, do not program the slot request bits without programming the
frame valid bits in ATAG register.
7. In gated clock mode, refer to Table 53-3.
8. Set CR[TE/RE] bits.
To ensure proper operation of the I²S, use the power-on or I²S reset before changing any
of the I²S control bits listed in the following table.
Note
These control bits should not be changed when the I²S module
is enabled
