Furthermore, please consider the following characteristics:
•
By default, the 3V3 power is in a disabled state. In your application, please use the function
Board_EnablePowerSupply3V3(EXTENSION_BOARD) to enable the 3V3 on the extension
bus.
•
The pins of the extension bus are protected against ESD up to 4kV. This includes a serial
resistance of 40ohm into the signal path. While this is no problem for communication, it
needs to be considered when powering external components via GPIO, e.g. an LED.
•
Any pin that you intend to use will have to be configured accordingly. Please refer to the
GPIO module for doing so. All pins are assigned with default modes and values in file
xdk110/Platform/BSP/source/BSP_BoardSettings.h.
Please refer to the interface for further
information.
•
Most of the pins provided on the extension bus can be freely configured, e.g. as GPIO, or
following the recommendations in the table below. However, the following pins differ
electrically from the standard:
o
Pins B9 and B10 are equipped with an internal pull-up resistor of 3.32kOhm and are
therefore usable for I2C communication only.
o
Pins PD5 and PD6 have anti-alias (low-pass) filters with a cut off frequency of ~400
MHz
