DAIEN: DAI Interface Enable
0 — DAI operation disabled, control of the SDIN, SDOUT, SCLKLRCK, and LRCK pins given to
the SSI2 / CODEC / DAI pin mulitiplexing logic to assign I/O pins 60-64 to another block.
1 — DAI operation enabled
Note that by default, the SSI / CODEC have precedence over the DAI interface in regard to the
use of the I/O pins. Nevertheless, when bit 3 (DAISEL) of register SYSCON3 is set to 1, then
the above mentioned DAI ports are connected to I/O pins 60–64.
ECS: External Clock Select selects external MCLK when = 1.
ReservedMust be 0.
LCTM: Left Channel Transmit FIFO Interrupt Mask
0 — Left Channel Transmit FIFO half-full or less condition does not generate an interrupt (LCTS
bit ignored).
1 — Left Channel Transmit FIFO half-full or less condition generates an interrupt (state of LCTS
sent to interrupt controller).
LCRM: Left Channel Receive FIFO Interrupt Mask
0 — Left Channel Receive FIFO half-full or more condition does not generate an interrupt
(LCRS bit ignored).
1 — Left Channel Receive FIFO half-full or more condition generates an interrupt (state of
LCRS sent to interrupt controller).
RCTM: Right Channel Transmit FIFO Interrupt Mask
0 — Right Channel Transmit FIFO half-full or less condition does not generate an interrupt
(RCTS bit ignored).
1 — Right Channel Transmit FIFO half-full or less condition generates an interrupt (state of
RCTS sent to interrupt controller).
RCRM: Right Channel Receive FIFO Interrupt Mask
0 — Right Channel Receive FIFO half-full or more condition does not generate an interrupt
(RCRS bit ignored).
1 — Right Channel Receive FIFO half-full or more condition generates an interrupt (state of
RCRS sent to interrupt controller).
