(3) Bus Cycle Time/Instruction Cycle Time

The LC866448B/44B/40B/36B/32B/28B/24B/20B/16B/12B/08B are constructed to read ROM twice within one

instruction cycle. It has 1.7 times more performance capability within the same instruction cycle compared to our 4-bit

microcomputers (LC66000 series).

Bus cycle time indicates the speed to read ROM.
