RMR Receive Message Ready
At least a threshold lenth of data has been stored in the B1_RFIFO.
RME Receive Message End
Used in transparent mode only. The last block of a frame has been received. The frame length can
be found in B1_RBCH + B1_RBCL registers. The number of data available in the B1_RFIFO equals
frame lenth modulus threshold. The result of CRC check is indicated by B1_STAR:CRCE bit.
When the number of last block of a frame equals the threshold, only RME interrupt is generated.
RDOV Receive Data Overflow
Data overflow occurs in the receive FIFO. The incoming data will overwrite the data in the receive
FIFO.
XFR Transmit FIFO Ready
This interrupt indicates that up to a threshold length of data can be written into the B1_XFIFO.
XDUN Transmit Data Underrun
This interrupt occurs when the B1_XFIFO has run out of data. In this case, the W6692 will
automatically reset the transmitter and send the inter frame time fill pattern on B channel. The
software must wait until transmit FIFO ready condition (via XFR interrupt), re-write data, and issue
XMS command to re-transmit the data.

Setting the bit to "1" masks the corresponding interrupt source in B1_EXIR register. Masked interrupt
status bits are read as zero when B1_EXIR register is read. They are internally stored and pending
until the mask bits are zero.
All the interrupts in B1_EXIR will be masked if the IMASK: B1_EXI bit is set to "1".
