Five independent external interrupts (NMI, IRL3 to IRL0)
15-level signed external interrupts: IRL3 to IRL0
On-chip peripheral module interrupts: Priority level can be set for each
module
Supports debugging by means of user break interrupts
Two break channels
Address, data value, access type, and data size can all be set as break
conditions
Supports sequential break function
Supports external memory access
⎯ 32/16/8-bit external data bus
External memory space divided into seven areas, each of up to 64
Mbytes, with the following parameters settable for each area:
⎯ Bus size (8, 16, or 32 bits)
⎯ Number of wait cycles (hardware wait function also supported)
⎯ Direct connection of DRAM, synchronous DRAM, and burst ROM
⎯ Supports fast page mode and DRAM EDO
⎯ Supports PCMCIA interface
⎯ Chip select signals (CS0 to CS6) output for relevant areas
DRAM/synchronous DRAM refresh functions
⎯ Programmable refresh interval
⎯ Supports CAS-before-RAS refresh mode and self-refresh mode
DRAM/synchronous DRAM burst access function
Big endian or little endian mode can be set
possible by setting space type
