3.
The AFE Control Board-SAM4C supports Atmel Software Framework (ASF) drivers and demo code. The
software program is developed in environment such as IAR Embedded Workbench for ARM .

Debugger

3.1
SAM-ICE can program and debug the AFE Control Board-SAM4C. Customer can also use other instruments for
programming and debugging. A JTAG debug port is designed on the AFE Control Board-SAM4C.

Power Supply

3.2
The AFE Control Board - SAM4C can be powered either by external DC 9V power source or extended connector
