Software Configuration

The SDRAM initialization sequence is described in the “SDRAM Device Initialization” section of

the SDRAM Controller.

Figure 25-3. 1 x 16-bit SDR-SDRAM Hardware Configuration

The following configuration must be respected:

The SDRAM initialization sequence is described in the “SDRAM Device Initialization” section of

the SDRAM Controller.

• Address lines A[2..11], A[13], BA0, BA1, SDA10, SDCS, SDWE, SDCKE, NBS1, RAS, CAS,

• Initialize the SDRAM Controller depending on the SDRAM device and system bus frequency.

• Address lines A[2..11], A[13-14], BA0, BA1, SDA10, SDCS, SDWE, SDCKE, NBS1, RAS,

• Initialize the SDRAM Controller depending on the SDRAM device and system bus frequency.

and data lines D[0..15] are multiplexed with PIO lines and thus dedicated PIOs must be

programmed in peripheral mode in the PIO controller.

CAS, and data lines D[0..15] are multiplexed with PIO lines and thus dedicated PIOs must be

programmed in peripheral mode in the PIO controller.
