RMB Receive Message Aborted
Used in transparent mode only. A "1" means that a sequence of
seven 1's was received and the
frame is aborted by the B1_HDLC controller. Software must issue RRST command to reset the
receiver.
Note
: Bit CRCE is valid only after a RME interrupt and remains valid until the frame is acknowledged via RACK command. RMB
must be polled after a RMR/RME interrupt.
XDOW Transmit Data Overwritten
At least one byte of data has been overwritten in the B1_XFIFO. This bit is cleared only by XRST
command.
XBZ Transmitter Busy
The B1_HDLC transmitter is busy when XBZ is read as "1". This bit may be polled. The XBZ bit is
active when an XMS command was issued and the message has not been completely transmitted.

MA17-10 Address Mask Bits
Used in transparent mode only. These bits mask the first byte address comparisons. If the mask bit is
"1", the corresponding bit comparison with B1_ADR1 is disabled.
0: Unmask comparison
1: Mask comparison
