Figure 29 Monitor Channel Access Directions
Setting SWST:MON to ’0’ disables the controller access to the Monitor channel (figure
29 upper left part).
Setting SWST:MON to ’1’ enables three different ways of controller access to the
Monitor channel. ADF2:TE1 set to ’0’ allows to either access the U-transceiver core of
the IEC-Q TE (see figure 29 upper right part, ADF2:MIN = ’1’) or the IOM-2 interface of
the IEC-Q TE (figure 29 lower left part, ADF2:MIN = ’0’).
Setting ADF2:TE1 to ’1’ in TE mode gives access to IOM-2 channel 1 rather than IOM-2
channel 0 directed out of the IEC-Q TE. This allows to program devices linked to IOM-2
channel 1 (e.g. ARCOFI) via the processor interface of the IEC-Q TE.
