3.17 CIF/EBC/RGMII/BT656 Extension Interfaces
The development board reserves CIF, EBC, RGMII, BT656 and other signal extension interfaces to facilitate users to
debug the corresponding peripherals. If you need to change the extension interface, jumper resistors are needed, and
you need to add the resistors corresponding to the signal, and remove the resistors accordingly. Due to the large
number of networks, it will not go into much details here.
