Right Channel Transmit FIFO Interrupt Mask (RCTM)
The right channel transmit FIFO interrupt mask (RCTM) bit is used to mask or enable the right channel
transmit FIFO service request interrupt. When RCTM = 0, the interrupt is masked and the state of the
right channel transmit FIFO service request (RCTS) bit within the DAI status register is ignored by the
interrupt controller. When RCTM = 1, the interrupt is enabled and whenever RCTS is set (one) an in-
terrupt request is made to the interrupt controller. Note that programming RCTM = 0 does not affect
the current state of RCTS or the right channel transmit FIFO logic
’
s ability to set and clear RCTS; it
only blocks the generation of the interrupt request.
5.16.1.6
Right Channel Receive FIFO Interrupt Mask (RCRM)
The right channel receive FIFO interrupt mask (RCRM) bit is used to mask or enable the right channel
receive FIFO service request interrupt. When RCRM = 0, the interrupt is masked and the state of the
right channel receive FIFO service request (RCRS) bit within the DAI status register is ignored by the
interrupt controller. When RCRM = 1, the interrupt is enabled and whenever RCRS is set (one) an
interrupt request is made to the interrupt controller. Note that programming RCRM = 0 does not affect
the current state of RCRS or the right channel receive FIFO logic
’
s ability to set and clear RCRS; it
only blocks the generation of the interrupt request.
5.16.1.7
Loop Back Mode (LBM)
The loop back mode (LBM) bit is used to enable and disable the ability of the DAI
’
s transmit and re-
ceive logic to communicate. When LBM = 0, the DAI operates normally. The transmit and receive data
paths are independent and communicate via their respective pins. When LBM = 1, the output of the
serial shifter (MSB) is directly connected to the input of the serial shifter (LSB) internally and control
of the SDOUT, SDIN, SCLK, and LRCK pins are given to the peripheral pin control (PPC) unit.
Table 48
shows the bit locations corresponding to the ten different control bit fields within the DAI con-
trol register. Note that the DAIEN bit is the only control bit which is reset to a known state to ensure
the DAI is disabled following a reset of the device. The reset state of all other control bits is unknown
and must be initialized before enabling the DAI. Writes to reserved bits are ignored and reads return
zeros.
