If the Autostart Jumper (J1) is inserted, the user program immediately restarts after a reset.
On delivery, the Autostart jumper is set. Please remove, otherwise no program transfer is pos-
sible.
Clock Generation
The clock generation of the microcontroller is performed by a 12 MHz quartz crystal. In the controller
the 12 MHz are clocked up to 66Mhz with a PLL-oscillator. All timings of the controller, as well as
the 48Mhz of the USB subsystem are derived from this clock.
Real-Time Clock
The C-Control Pro AVR32Bit Unit has a separate oscillator with a 32.768 kHz clock crystal. This
precise quartz watch can be set and read by software. This clock is ideal for applications such as
time-accurate timers, etc.
Digital Ports
The C-Control Pro AVR32Bit module has 57 digital inputs and outputs that can be used with special
functions such as PWM, ADC, etc. depending on the configuration. You can connect the digital in-
puts/outputs to for e.g. buttons with pull-up/pull-down resistors, digital ICs, optocouplers or driver cir-
cuits that are connected to relays. The pins are addressed individually, bitwise in each port. Each
pin can be either input or output.
Never connect two pins that are configured as outputs at the same time. This can des-
troy the C-Control Pro AVR32Bit UNIT!
Digital input pins are high impedance or connected with an internal pull-up/pull-down resistors and
lead an applied voltage signal to a logical value. The prerequisite is that the signal voltage is within
the specified range for low or high level. In the further processing of the program, the logical values of
individual input pins are represented as 0 ("low"), or 1 ("high"). Output ports can output digital voltage
signals via an internal driver circuit. Connected circuits can draw a certain current of the ports (at
high level) or supply in these (at low level).
Never connect a voltage greater than 3.6V to one of the pins of the C-Control Pro
AVR32Bit UNIT!
Note the maximum load current for a single port and for all ports in total. Exceeding the maximum
values can lead to the destruction of the C-Control Pro AVR32Bit module. After a reset each pin is
initially configured as input. Use certain functions to change the data direction.
