Software Configuration
The SDRAM initialization sequence is described in the “SDRAM Device Initialization” section of
the SDRAM Controller.
Figure 24-3. 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.
