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 internal bus
masters; CPU, DMAC, and DTC.
6.1
• Manages external address space in area units
• Basic bus interface
• Byte control SRAM interface
• Burst ROM interface
• Address/data multiplexed I/O interface
Manages the external address space divided into eight areas
Chip select signals (CS0 to CS7) can be output for each area
Bus specifications can be set independently for each area
8-bit access or 16-bit access can be selected for each area
Burst ROM, byte control SRAM, or address/data multiplexed I/O interface can be set
An endian conversion function is provided to connect a device of little endian
This interface can be connected to the SRAM and ROM
2-state access or 3-state access can be selected for each area
Program wait cycles can be inserted for each area
Wait cycles can be inserted by the WAIT pin.
Extension cycles can be inserted while CSn is asserted for each area (n = 0 to 7)
The negation timing of the read strobe signal (RD) can be modified
Byte control SRAM interface can be set for areas 0 to 7
The SRAM that has a byte control pin can be directly connected
Burst ROM interface can be set for areas 0 and 1
Burst ROM interface parameters can be set independently for areas 0 and 1
Address/data multiplexed I/O interface can be set for areas 3 to 7
