8.2 Configuration Examples
8.2.1 General Settings
All of the following board configurations are based on these conditions:
•
Normal device operation mode (JP41[OPEN]: FLMD0 = L).
•
All voltages for all functions are activated.
•
Current measurements are not carried out, hence JP4, JP5, JP30 and JP31 are set.
•
Clock supply: assuming one of the resonators, coming with the board, are plugged into X1 socket.
•
For connection to external power supplies the 'banana-type' connectors CN8 (GND), CN9 (+5.0 V) and CN10 (+3.3
V) are assembled on the board.
•
If also the core supply voltage of 1.12 V will be supplied from an external power supply the connector CN11
(included in the package) must be assembled on the board.
8.2.2 Jumper Indicators
•
The green jumper JP41 for FLMD0 must always be open for a ‘normal’ (user mode and debug) operation of the
device.
•
The red jumpers are related to the power supply configuration.
Following jumper symbols are used:
−
: Jumper must not be set.
−
: Jumper must be set in the indicated position, in this case position [2-3]
−
: Jumper can be set to position [1-2] or position [2-3]
−
: Jumper with optional setting. The red setting [2-3] is the default setting. The blue setting [1-2] is the
optional setting.
Note
The pin 1 of a jumper can be identified by
•
a small circle near the jumper
•
a square soldering pad.
