Notes:
1. These I/Os are shared with the USART of the (optional) WILC3000 module for its Bluetooth functionality. The
two interfaces cannot work together and the user should pay particular attention to impedance adaptation on
each node. The series resistor can be removed to improve behavior.
2. These I/Os are shared with the GMAC interface of the KSZ8081 (Ethernet 10/100) interface. The user should
pay particular attention to impedance adaptation on each node. The series resistor can be removed to improve
behavior.
3. This interface is shared with the mikroBUS1 and mikroBUS2 interfaces. The end user must pay attention to
the I²C addresses used on these nodes.
3.4.6 RPi CSI Camera Interface
The SAMA7G54-EK board features a MIPI CSI camera connector (Raspberry Pi compatible).
