Table 6-26 below details the function of the switches associated with the SDRAM.
Table 6-26: External BUS & SDRAM Configuration Switch Settings
SW6-1
Explanation
ON
Enable the external bus signal.*
1
OFF
Enables signals other than the external bus. (CAN, Emulator, I
2
C, etc.)
*
1
: SDRAM and Ethernet / Switch / EtherCAT port 2 cannot be used at the same time.
Table 6-27 below details the function of the jumpers associated with the SDRAM.

Explanation
CN17
Shorted Pin 1-2
Connect 3.3V Power rail to VCC1833_2. (When using SDRAM)
*1
Shorted Pin 2-3
Connect 1.8V Power rail to VCC1833_2. (When using Ethernet port 2)
*1
: When using SDRAM, use the Ethernet switch (CN18-CN20) setting at 2-3.
