: In the default RSK+ configuration, ETH2_REFCLK_G signal is not connected to the XTAL1 pin of the
Ethernet controller IC (IC16). If you want to connect the external clock (X1) on the RSK+ to the Ethernet
controller IC, configure as shown in Table 6-33 above.
Table 6-34 below details the function of the switches associated with the Ethernet.
