ConnRefSts 9398-9399 The status of the last refused connection. The
upper byte of 9399 contains the general status.
The lower byte of 9399 contains the length of
the extended status, either 0 (no extended
status) or 2. Register 9398 contains the
extended status, if present.

The Error Log
Registers 9336-9339 contain the error log. This is a log of the source
addresss for the last eight messages with CRC errors or transmit abort
errors. Each register contains two error log entries, one byte each.
NOTE: Since these errors occur when the MBCN receives bad packets,
the contents of the log may not be valid, but it may be useful in
identifying problem nodes.
The error log is a ring buffer.
