Of the 64 MB (linear) address space, the lower 16 MB (0000000H to 0FFFFFFH) include four chip select functions,
By using these chip select functions, the memory block can be divided to enable effective use of the memory
The V850ES/SA2 and V850ES/SA3 include the following two external bus interface modes.
• Multiplexed bus mode
• Separate bus mode
These two modes can be selected by using the external bus interface mode control register (EXIMC).
(1) External bus interface mode control register (EXIMC)
External Bus Interface Mode Control Function
This register can be read or written in 8-bit or 1-bit units.
This register is cleared to 00H after reset.
