Disconnect Event
This field contains a 16-bit counter that increments for
each disconnect event. The counter stops when full
(and does not roll over) and self-clears on read
In repeater mode, a frame that starts without “JK” is a
disconnect event.

Receive Error
Frame
This field contains a 16-bit counter that increments
once per frame for any receive error condition (such
as a symbol error or premature end of frame) in that
frame. The counter stops when full (and does not roll
over) and self-clears on read.
