118 / 700 page  Section 6 Bus Controller 6.1 Overview The H8/3002 has an on-chip bus controller that divides the address space into eight areas and can assign different bus specifications to each. This enables different types of memory to be connected easily. A bus arbitration function of the bus controller controls the operation of the DMA controller (DMAC) and refresh controller. The bus controller can also release the bus to an external device. 6.1.1 Features Features of the bus controller are listed below. • Independent settings for address areas 0 to 7 — 128-kbyte areas in 1-Mbyte modes; 2-Mbyte areas in 16-Mbyte modes. — Chip select signals (CS0 to CS3) can be output for areas 0 to 3. — Areas can be designated for 8-bit or 16-bit access. — Areas can be designated for two-state or three-state access. • Four wait modes — Programmable wait mode, pin auto-wait mode, and pin wait modes 0 and 1 can be selected. — Zero to three wait states can be inserted automatically. • Bus arbitration function — A built-in bus arbiter grants the bus right to the CPU, DMAC, refresh controller, or an external bus master. 103 |
