The ISAC-SX TE supports a serial or a parallel microcontroller interface. For applications
where no controller is connected to the ISAC-SX TE microcontroller interface
programming is done via the IOM-2 MONITOR channel from a master device. In such
applications the ISAC-SX TE operates in the IOM-2 slave mode (refer to the
corresponding chapter of the IOM-2 MONITOR handler). This mode is suitable for
control functions (e.g. programming registers of the S/T transceiver), but the bandwidth
is not sufficient for access to the HDLC controllers.
The interface selections are all done by pinstrapping (see
are evaluated when the reset input RES is active. For the pin levels stated in the tables
the following is defined:
’High’, ’Low’: dynamic pin; value must be ’High’ or ’Low’ only during reset

Table 3
Note: For a selected interface mode which doesn’t need all input selection and address
The interfaces contain all circuitry necessary for the access to programmable registers,
status registers and HDLC FIFOs. The mapping of all these registers can be found in
Chapter
The microcontroller interface also provides an interrupt request at pin INT which is low
active by default but can be reprogrammed to high active, a reset input pin RES and a
reset output pin RSTO.
The interrupt request pin INT becomes active if the ISAC-SX TE requests an interrupt
and this can occur at any time.
