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.
