2.3.1.3.1 MATRIX Configuration for MPDDRC Single Port Setting (Default)
The default configuration is single port, with all devices accessed on D0-D15: SDRAM and/or NAND Flash and/or SMC. This configuration is the Reset state SFR_CCFG_EBICSA.DDR_MP_EN = 0.
As the DDRC multiport feature is disabled, all hosts access DDR-SDRAM using MATRIX Client 1 (MPDDRC port 0), sharing it with EBI accesses.
The NAND Flash can be located either on D0-D7 or on D16-D23 depending on SFR_CCFG_EBICSA.NFD0_ON_D16, respectively 0 (default) or 1.
