2.1
The SCOUT supports a serial microcontroller interface. For applications where no
controller is connected to the SCOUT microcontroller interface programming is done via
the IOM-2 MONITOR channel from a master device. In such applications the SCOUT
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 or a reset
of the undervoltage detection is released. For the pin levels stated in the tables the
following is defined:
’High’:
V
Table 2
Interface Selection
The mapping of all accessible registers can be found in figure 82 in chapter 7.
The microcontroller interface also consists of a microcontroller clock generation at pin
MCLK and an interrupt request at pin INT.
