Solderable Pin Bridges
Some resistor bridges enable/disable or changing functions of specific signals in Table 2.
To disable the signals, the resistors have to be removed. To enable, the resistor has to be assembled.
For example
: Desoldering the intialy assembled resistor R33, disables the Potentiometer and the analog Signal
AN0 of the Aurix, making it usable for other purposes.

Arduino Compatible Connector
The mapping of GPIOs and Aurix
™ pin functions to Arduino compatible functions can be found in Figure 5. The
Arduino compatible connector supports
SPI interface (SPI_xxx)
I2C interface (I2C_xxx)
UART interface (UART_xxx)
PWM signal outputs (PWM0-13)
ADC input (ADC0-5)
Interrupt input (INT0-1)
Note that all pins are cabable of offering more functions than mentioned in Figure 5. For more information about
all pin functions, we want to refer you to the
