Data Sheet
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 SCOUT-DX. 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.
Figure 24 shows an example for an abort requested by the receiver, Figure 25 shows
an example for an abort requested by the transmitter and Figure 26 shows an example
for a successful transmission.
