6.1
The H8/3006 and H8/3007 have an on-chip bus controller (BSC) that manages the external
address space divided into eight areas. The bus specifications, such as bus width and number of
access states, can be set independently for each area, enabling multiple memories to be connected
easily.
The bus controller also has a bus arbitration function that controls the operation of the internal bus
masters-the CPU, DMA controller (DMAC), and DRAM interface and can release the bus to an
external device.
6.1.1
The features of the bus controller are listed below.
• Manages external address space in area units
• Basic bus interface
• DRAM interface
⎯ Manages the external space as eight areas (0 to 7) of 128 kbytes in 1M-byte modes, or 2
⎯ Bus specifications can be set independently for each area
⎯ DRAM/burst ROM interfaces can be set
⎯ Chip select (CS
⎯ 8-bit access or 16-bit access can be selected for each area
⎯ Two-state access or three-state access can be selected for each area
⎯ Program wait states can be inserted for each area
⎯ Pin wait insertion capability is provided
⎯ DRAM interface can be set for areas 2 to 5
⎯ Row address/column address multiplexed output (8/9/10 bits)
⎯ 2-CAS byte access mode
⎯ Burst operation (fast page mode)
⎯ T
