Operation Mode Selection

The piggyback board gives the possibility to configure the following jumpers for selection of the device operation
mode:
Table 6.1 Device operation mode selection jumpers (cont'd)
Jumper Function
JP38 MODE0 pin level
•
JP38[2-1]: MODE0 = H level
•
JP38[2-3]: MODE0 = GND
JP41 FLMD0 pin level
•
JP41[SHORT]: FLMD0 = H level
•
JP41[OPEN]: FLMD0
−
controlled by debugger or programming tool, if a tool is connected via CN4
−
GND, if no tool connected
JP39 FLMD1 pin level
•
JP39[SHORT]: FLMD1 = H level
•
JP39[OPEN]: FLMD1 = GND
JP40 FLMD2 pin level
•
JP40[2-1]: FLMD2 = H level
•
JP40[2-3]: FLMD2 = GND
CAUTION
Be careful in configuration of the operation mode related pins. The wrong configuration and
operation of the device outside of its specification can cause irregular behavior of the device and
long-term damage cannot be excluded. Be sure to check the corresponding Hardware User's Manual
for details, which modes are specified for the used device.
Note
In most cases the 'normal operating mode' of the device will be used.
This mode is for execution of the user program. The on-chip debug functions also use this mode.
To select the 'normal operating mode' of the device, the FLMD0 pin must be pulled low. To do so, remove
the jumper JP41.
All other jumpers related to the mode selection can be left open.
