- 32-bit address bus
- 32-bit data bus (bidirectional D | unidirectional DIN/DOUT)
- byte, halfword or word addressable
- Non-squential: request transfer where no correlation to previous cycle
- Sequential: request transfer where either the same or one word/halfword after preceeding cycle' address
- Internal: no transfer (internal function) -> no useful prefetching at the same time
- Coprocessor register: request transfer to communicate with coprocessor
