| + | == DRAM Windows == | ||
| + | * 8-bit BASE & SIZE registers | ||
| + | * BASE corresponds to address bits [31:24] | ||
| + | * Min. SIZE (0x01) = 16MB; max. SIZE (0xFF) = 4GB | ||
| + | * SIZE is a mask; only 8 legal values (0x01, 0x03, 0x07, 0x0F, etc.) | ||
| + | == Register Window == | ||
| + | * Fixed SIZE of 1MB | ||
| + | * BASE register | ||
| + | == Configurable Windows == | ||
| + | * 16-bit BASE & SIZE registers | ||
| + | * BASE corresponds to address bits [31:16] | ||
