this register, M13_RDL_DATA_R. On reset, the FIFO is emp-
tied, and reading from this register returns an undetermined
value.
Reserved.
The number of bytes in the frame modulo-128 is indicated by
this register. This is the number of bytes from the frame that
have been written into the FIFO, not the number of bytes
remaining in the FIFO. All bytes between the opening flag and
the FCS bytes are included (unless M13_RDL_FCS

This bit is high if the closing flag or an abort byte has been
received.
This bit is high if the frame was ended with an abort byte
rather than a closing flag.

This bit is set if at least 1 byte of the frame was overwritten by
a byte from a succeeding frame before being read.
