3.3V and the GND pins are connected to each other! The "POWER" LED indicates that the Unit is

receiving power.

The C-Control PRO UNIT has no inverse polarity protection, so the UNIT is destroyed by

reversed polarity of the power supply!

USB

Through the mini-USB connector, the C-Control Pro AVR32Bit module is connected to the PC. The

USB port is used for programming and debugging of user software. All C-Control Pro UNIT's have a

debugger. The debugger can set breakpoints and variables can be monitored and analyzed at

runtime.

The module is not supplied with power via USB!

Reset

A reset causes the return of the micro-controller system in an initial state. The C-Control Pro Module

AVR32Bit knows basically three sources of reset:

Power-on reset: Executed automatically after switching on the operating voltage. The UNIT is then

again in bootloader mode. It can be reset or a new module is transferred to the interpreter unit.

Brown-out Reset: Automatically runs when the core voltage is less than 1.65V. This prevents the

controller unit to get in undefined states at a drop of the supply voltage. If the voltage is signific-

antly higher again, then the module starts anew.

Hardware reset: Executed when the RESET button of the module is pressed.

Start/Stop Button

With the start/stop button, the program will start. In a renewed pressure, the program is stopped. A

stop with this is preferable to the reset button, as with a reset, the USB subsystem is started again

from scratch and the connection is renegotiated. Is the Autostart Jumper (J1) is inserted, the applic-

ation is started directly after a reset and the start/stop button remains without effect.
