3.1
This LSI supports two types of operating mode (modes 6 and 7). Pin functions are changed
according to each operating mode. The operation mode is determined by the setting of mode pins
(MD2 to MD0). Mode 6 is the external expansion mode, which allows external memory and
peripheral device to be accessed. In external expansion mode, the bus controller sets address space
of 8 bits or 16 bits for each area after the program is started to execute. Making one of the areas a
16-bit address space leads to 16-bit bus mode and making all the area 8-bit access space leads to
8-bit bus mode.
In mode 7, the external address space cannot be used. Mode pins should not be changed during
operations.
