2.1
Depending of the package the SCOUT supports a serial or a parallel microcontroller
interface. In the P-MQFP-44 package only a serial interface is supported whereas in the
P-MQFP-64 package either a serial or a parallel microcontroller interface can be
selected.
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 for the P-MQFP-44 package and in table 3 for the P-MQFP-64
package. 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
