Address: 0x8000.2000, Read / Write
Bit Descriptions:
(See f ull bit descriptions for complete details)
[0:15]: Reserved. M ust be set to 0x0404
DAIEN: DAI Interface Enable (See additional n otes for m ore detai l)
0-DAI operation disabled. Control of SDIN,SDOU T,SCLK and
LRCLK given to the SSI2/CODEC/DA I multiplexor to assign
pins to another block
1-DAI operation enable.
Note: The SSI/CODEC by default have precedence of the DAI interface in regards to
the use of the I/O pins.
