Raw Interrupt Status. The AC97ISR registers are the raw Interrupt status
registers for the controller FIFOs. All bits are cleared to zero on reset except
for the TCIS as the FIFO and shift register should both be empty. Any write to
this register clears the overrun error.

TXBUSY is set when TEN = “1” AND there is data in the
FIFO, OR when data from this FIFO is being sent in the
current frame.
TXBUSY is cleared at the start of the next frame following
the assertion of the corresponding channel’s TXFE flag
(the value of TEN is irrelevant).
Transmit FIFO full flag, active HIGH.
This bit is asserted HIGH if the transmit FIFO is full.
Receive FIFO full flag, active HIGH.
This bit is asserted HIGH if the receive FIFO is full.
Transmit FIFO empty flag, active HIGH.
This bit is asserted HIGH if the transmit FIFO is empty.
Receive FIFO empty flag, active HIGH.
This bit is asserted HIGH if the receive FIFO is empty.
Reserved. Unknown During Read.
RX Interrupt Status - This bit is set to “1” if the receive
FIFO becomes half full.
TX Interrupt Status - This bit is set to “1” if the transmit
FIFO becomes half empty.
