The bus state controller (BSC) divides up the address spaces and outputs control for various types
of memory. This enables memories like SRAM and ROM to be linked directly to the chip without
external circuitry.
9.1
The BSC has the following features:
• Address space is divided into four spaces
• On-chip ROM and RAM interfaces
Figure 9.1 shows the BSC block diagram.
 A maximum linear 256-kbyte bus width (8 bits) for both on-chip ROM enabled mode and
 Wait states can be inserted by software for each space
 Wait state insertion with WAIT pin in external memory space access
 Outputs control signals for each space according to the type of memory connected
 On-chip ROM and RAM access of 32 bits in 1 state
on-chip ROM disabled mode, as for address space CS0
