The registers of the DFE-Q V2.1 are accessed via the Monitor channel of the IOM
interface. This chapter summarizes the available Monitor commands and messages.
Please refer to
procedure.
Monitor commands supported by the DFE-Q V2.1 are divided into three categories. Each
category derives its name from the first nibble (4 bits) of the two byte long message.
These are MON-0, MON-2 and MON-8. All monitor messages representing similar
functions are grouped together.
A special Monitor class are MON-12 commands which exist beside the known classes
listed above. By MON-12 commands it is possible to address internal registers directly.
MON-12 commands are always prioritized and are acknowledged first. See
Chapter 3.2.5
5.1
MON-0 messages are used to write and read the registers containing the information of
the EOC-channel on the U-interface. It is important to note that MON-0 messages
provide only access to the device internal EOC-registers. The insertion and extraction of
a message on the U-frame is handled automatically by the EOC-processor of the device.
The EOC is controlled and monitored via MON-0 commands and messages in the IOM
2 Monitor channel. MON-0 commands may be passed at any instant and need to be
transferred only once (applicable for auto and transparent mode). Code repetition is
performed within the chip by the EOC-processor. For more information about the EOC
processor and a detailed description of EOC auto/ transparent mode please see
Chapter
The structure of a MON-0 message is shown below. The structure is identical in EOC
auto and transparent mode.
