* 1 : 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.
Table 6-34: Ethernet Configuration Switch Settings
SW6-1 Explanation
ON Enable the external bus signal and Ethernet. *
1
OFF Enables signals other than the external bus. (CAN, Emulator, I 2 C, etc.)
* 1 : BUS (SDRAM) and Ethernet port 2 cannot be used at the same time.
Table 6-35 and Table 6-36 below details the function of the jumpers associated with the Ethernet.
Table 6-35: Ethernet Configuration Jumper Settings (1)
Reference Jumper Position Explanation
CN17
Shorted Pin 1-2 Connect 3.3V Power rail to VCC1833_2. (When using SDRAM)
Shorted Pin 2-3 Connect 1.8V Power rail to VCC1833_2. (When using Ethernet port 2)
Table 6-36: Ethernet Configuration Jumper Settings (2)
Reference Jumper Position Explanation
CN18, CN19,
CN20
Shorted Pin 1-2 When using 3 ports in the same PHY mode
Shorted Pin 2-3 When ports 0 and 1 use the same PHY mode and port 2 uses different PHY modes
* : When using VCC1833_2 at 3.3 V, use a jumper setting of 2-3.
