4.3.1 SDRAM Disable (JP1)
JP1 is used to enable or disable the third SDRAM device. When this jumper is
installed, the ADSP-21161N can access the SDRAM as 48-bit wide external
memory.
The upper 16 bits of data are multiplexed with the Link Ports and the external
data bus. Therefore when the jumper is installed the Link Ports are not available.
To use the Link Ports this jumper must be removed.
