6.1
The H8/3052BF 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 of the bus controller are listed below.
Independent settings for address areas 0 to 7
Four wait modes
Bus arbitration function
128-kbyte areas in 1-Mbyte modes; 2-Mbyte areas in 16-Mbyte modes.
Chip select signals (CS
Areas can be designated for 8-bit or 16-bit access.
Areas can be designated for two-state or three-state access.
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.
A built-in bus arbiter grants the bus right to the CPU, DMAC, refresh controller, or an
external bus master.
