The SBCX-X supports a serial micrcontroller interface. For applications where no
controller is connected to the SBCX-X programming is done via the IOM-2 MONITOR
channel from a master device. In such applications the SBCX-X 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 to transfer B- and D-channel data.
The interface selection is done by pinstrapping of the chip select signal CS (see

The interfaces contain all circuitry necessary for the access to programmable registers.
The mapping of all these registers can be found in
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 SBCX-X requests an interrupt and
this can occur at any time.
