x_SR—Status Register (Modem—D30:F3)
I/O Address:
Default Value:
Lockable:
Software can read the registers at offsets 04h, 05h and 06h simultaneously by
performing a single, 32-bit read from address offset 04h. Software can also read this
register individually by doing a single, 16-bit read to offset 06h. Reads across DWord
boundaries are not supported.

FIFO Error (FIFOE) — R/WC.
0 = Software clears this bit by writing a 1 to it.
1 = FIFO error occurs.
Modem in: FIFO error indicates a FIFO overrun. The FIFO pointers don't increment,
the incoming data is not written into the FIFO, thereby being lost.
Modem out: FIFO error indicates a FIFO underrun. The sample transmitted in this
case should be the last valid sample.

Buffer Completion Interrupt Status (BCIS) — R/WC.
0 = Software clears this bit by writing a 1 to it.
1 = Set by the hardware after the last sample of a buffer has been processed, AND if

0 = Software clears this bit by writing a 1 to it.
1 = Set by hardware when last valid buffer has been processed. It remains active until

cleared by software. This bit indicates the occurrence of the event signified by the
last valid buffer being processed. Thus, this is an event status bit that can be
cleared by software once this event has been recognized. This event will cause an
interrupt if the enable bit in the Control Register is set. The interrupt is cleared
when the software clears this bit.
In the case of transmits (PCM out, Modem out) this bit is set, after the last valid
buffer has been fetched (not after transmitting it). While in the case of Receives,
this bit is set after the data for the last buffer has been written to memory.

pointed to by the CIV has been processed (i.e., after the last valid buffer has been
processed). This bit is very similar to bit 2, except, this bit reflects the state rather
than the event. This bit reflects the state of the controller, and remains set until
the controller exits this state.
engines are idle, or it could happen once the controller has processed the last valid
