Features
– Write buffering for PCI and processor accesses
– Normal parity, read-modify-write (RMW), or ECC
– Data-path buffering between memory interface and processor
– Low-voltage TTL logic (LVTTL) interfaces
– 272 Mbytes of base and extended ROM/Flash/PortX space
– Base ROM space for 8-bit data path or same size as the SDRAM data path (32- or 64-bit)
– Extended ROM space for 8-, 16-, 32-bit gathering data path, 32- or 64-bit (wide) data path
– PortX: 8-, 16-, 32-, or 64-bit general-purpose I/O port using ROM controller interface with
programmable address strobe timing, data ready input signal (DRDY), and 4 chip selects
— 32-bit PCI interface
– Operates up to 66 MHz
– PCI 2.2-compatible
– PCI 5.0-V tolerance
– Dual address cycle (DAC) for 64-bit PCI addressing (master only)
– Accesses to PCI memory, I/O, and configuration spaces
– Selectable big- or little-endian operation
– Store gathering of processor-to-PCI write and PCI-to-memory write accesses
– Memory prefetching of PCI read accesses
– Selectable hardware-enforced coherency
– PCI bus arbitration unit (five request/grant pairs)
– PCI agent mode capability
– Address translation with two inbound and outbound units (ATU)
– Internal configuration registers accessible from PCI
— Two-channel integrated DMA controller (writes to ROM/PortX not supported)
– Direct mode or chaining mode (automatic linking of DMA transfers)
– Scatter gathering—Read or write discontinuous memory
– 64-byte transfer queue per channel
– Interrupt on completed segment, chain, and error
– Local-to-local memory
– PCI-to-PCI memory
