A dedicated Local-bus interface
⎯ Controls the external memory space divided into seven 64-Mbyte
⎯ The interface type, bus width, and wait-cycle insertion can be set for
SRAM interface
⎯ Wait-cycle insertion can be set by register values.
⎯ Wait-cycle insertion by the RDY pin
⎯ Connectable as area 0, 1, 2, 3, 4, 5, or 6
⎯ Selectable bus width: 64-/32-/16-/8-bit
Burst ROM interface
⎯ Wait-cycle insertion can be set by register values.
⎯ Number of units in burst transfers can be set by register values.
⎯ Connectable as area 0, 1, 2, 3, 4, 5, or 6
⎯ Selectable bus width: 64-/32-/16-/8-bit
MPX interface
⎯ Address/data multiplexing
⎯ Connectable as area 1 or 4
⎯ Selectable bus widths: 64-/32-bit
SRAM interface with byte-control
⎯ Connectable as area 1 or 4
⎯ Selectable bus width: 64-/32-/16-bit
PCMCIA interface (only for little-endian mode)
⎯ Wait-cycle insertion can be set by register values.
⎯ Bus-sizing function for adaptation to the I/O bus width
⎯ Connectable as area 5 or 6
⎯ Selectable bus width: 16-/8-bit
Supports transfer to and from E-IDE/ATAPI devices (ATA3)
⎯ Supports PIO mode 4 type and multi-word DMA mode 2 type
