2.1
The SCOUT-DX supports a serial microcontroller interface. For applications where no
controller is connected to the SCOUT-DX microcontroller interface programming is done
via the IOM-2 MONITOR channel from a master device. In such applications the
SCOUT-DX operates in the IOM-2 slave mode (refer to the corresponding chapter of the
IOM-2 MONITOR handler).
The interface selections are all done by pinstrapping. The possible interface selections
are listed in table 2. The selection pins are evaluated when the reset input RST is
released. For the pin levels stated in the tables the following is defined:
’High’:
V

The mapping of all accessible registers can be found in figure 76 in chapter 7.
The microcontroller interface also consists of a microcontroller clock generation at pin
MCLK and an interrupt request at pin INT.
