5.3.1 Chip select control function
Of the 64 MB (linear) address space, the lower 4 MB (0000000H to 03FFFFFH) include two chip select
control functions, CS0 and CS1. The areas that can be selected by CS0 and CS1 are fixed. as shown in
Table 5-3. By using these chip select control functions, the memory block can be divided to enable
effective use of the memory space.
However, since the V850E/RS1 has sixteen address pins (PDL0/AD0 to PDL15/AD15), 64 KB
addresses can be selected linearly.
