SDRAM Controller
Error Corrected Code Controller
I/O Drive Selection
The purpose of this control is to adapt the signal to the frequency. Two bits enable the user to
select High or Low Drive for memory data/addresses/control signals.
Setting the EBI_DRIVE field [17:16] in the EBI Chip Select Assignement Register (EBI_CSA)
located in the Chip Select Interface of the Bus Matrix, enables control of the EBI.
