• To control this handshake procedure a collision detection mechanism is implemented
• Monitor data will be transmitted repeatedly until its reception is acknowledged or the
• Two frames with the MX bit in the inactive state indicates the end of a message
• Transmission and reception of monitor messages can be performed simultaneously.
3.7.3.2
In case the SBCX-X does not detect identical monitor messages in two successive
frames, transmission is not aborted. Instead the SBCX-X will wait until two identical bytes
are received in succession.
A transmission is aborted of the SBCX-X if
• an error in the MR handshaking occurs
• a collision on the IOM-2 bus of the MONITOR data or MX bit occurs
• the transmission time-out timer expires
A reception is aborted by the device if
• an error in the MX handshaking occurs or
• an abort request from the opposite device occurs
MX/MR Treatment in Error Case
In the master mode the MX/MR bits are under control of the microcontroller through MXC
or MRC, respectively. An abort is indicated by an MAB interrupt or MER interrupt,
respectively.
In the slave mode the MX/MR bits are under control of the device. An abort is always
indicated by setting the MX/MR bit inactive for two or more IOM-2 frames. The controller
must react with EOM.

(EOM).
This feature is used by the SBCX-X to send back the response before the
transmission from the controller is completed (the SBCX-X does not wait for EOM
from controller).
