DAI Control Register (DAIR)
Address:
0x8000.2000, Read / Write
Bit Descriptions:
(See full bit descriptions for complete details)
[0:15]:
Reserved. Must be set to 0x0404
DAIEN:
DAI Interface Enable (See additional notes for more detail)
0-DAI operation disabled. Control of SDIN,SDOUT,SCLK and
LRCLK given to the SSI2/CODEC/DAI 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.
ECS:
1=for 64 Fs mode. Bit is ignored in 128 Fs mode.
LCTM:
Left Channel Transmit FIFO Interrupt Mask.
0=Left Channel Transmit FIFO half-full or less condition does not
generate and interrupt. LCTS is ignored
1=Left Channel Transmit FIFO half-full or less condition does
generate and interrupt. LCTS status sent to interrupt controller
LCRM:
Left Channel Receive FIFO Interrupt Mask.
0=Left Channel Receive FIFO half-full or less condition does not
generate and interrupt. LCTS is ignored
1=Left Channel Receive FIFO half-full or less condition does
generate and interrupt. LCTS status sent to interrupt controller.
RCTM:
Right Channel Transmit FIFO Interrupt Mask.
0=RightChannel Transmit FIFO half-full or less condition does not
generate and interrupt. RCTS is ignored
1=Right Channel Transmit FIFO half-full or less condition does
generate and interrupt. RCTS status sent to interrupt controller
RCRM:
Right Channel Receive FIFO Interrupt Mask.
0=Right Channel Receive FIFO half-full or less condition does not
