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.
