This LSI has an on-chip bus controller (BSC) that manages the external address space divided into
eight areas.
The bus controller also has a bus arbitration function, and controls the operation of the bus
mastership⎯the CPU, DMA controller (DMAC), EXDMA controller (EXDMAC) * , and data
transfer controller (DTC). A block diagram of the bus controller is shown in figure 6.1.
Note: * The EXDMAC is not supported by the H8S/2375, H8S/2375R, H8S/2373, and
6.1
• Manages external address space in area units
• Basic bus interface
• Burst ROM interface
• DRAM interface
• Synchronous DRAM interface *
• Bus arbitration function
Note: * The Synchronous DRAM interface is not supported by the H8S/2378 Group.
BSCS201A_010020020400
Manages the external address space divided into eight areas of 2 Mbytes
Bus specifications can be set independently for each area
Burst ROM, DRAM, or synchronous DRAM interface * can be set
Chip select signals (CS0 to CS7) can be output for areas 0 to 7
8-bit access or 16-bit access can be selected for each area
2-state access or 3-state access can be selected for each area
Program wait states can be inserted for each area
Burst ROM interface can be set independently for areas 0 and 1
DRAM interface can be set for areas 2 to 5
Continuous synchronous DRAM space can be set for areas 2 to 5
Includes a bus arbiter that arbitrates bus mastership between the CPU, DMAC, DTC, and
EXDMAC
