Specification


ROM cache

Instruction/data separation system

Instruction prefetch cache: Full/set associative

Instruction prefetch miss cache: Full/set associative

Data cache: Full/set associative

Line size: 16 bytes

Hardware prefetch function (continuous/branch prefetch)

Interrupt controller

Nine external interrupt pins (NMI and IRQ7 to IRQ0) (INTC)

On-chip peripheral interrupts: Priority level set for each module 16 priority levels available

Register bank enabling fast register saving and restoring in interrupt processing

Bus state controller

Address space divided into eight areas (0 to 7), each a maximum of 64 (BSC) Mbytes

External bus: 8 or 16 bits

The following features settable for each area independently

⎯ Supports both big endian and little endian for data access

Bus size (8 or 16 bits): Available sizes depend on the area.

⎯ Number of access wait cycles (different wait cycles can be

specified for read and write access cycles in some areas)

⎯ Idle wait cycle insertion (between same area access cycles or different area access cycles)

⎯ Specifying the memory to be connected to each area enables

direct connection to SRAM, SRAM with byte selection, SDRAM,

and burst ROM (clocked synchronous or asynchronous). The

address/data multiplexed I/O (MPX) interface is also available.

⎯ Outputs a chip select signal (CS0 to CS7) according to the target

area (CS assert or negate timing can be selected by software)

SDRAM refresh

Auto refresh or self refresh mode selectable

SDRAM burst access
