generation when operand data in the data space is accessed. The address stored in this pointer ±32 KB can be directly
accessed by an instruction for operand data. Because the number of general-purpose registers that can be used as a
pointer is limited, however, by keeping the performance from dropping during address calculation when a pointer value is
changed, as many general-purpose registers as possible can be secured for variables, and the program size can be
reduced.

The architecture of the V850ES/JF3-L requires that a register that serves as a pointer be secured for address
(1) Program space
Of the 32 bits of the PC (program counter), the higher 6 bits are fixed to 0, and only the lower 26 bits are valid.
Regarding the program space, therefore, a 64 MB space of contiguous addresses starting from 00000000H
unconditionally corresponds to the memory map.
To use the internal RAM area as the program space, access the following addresses.
Caution If a branch instruction is at the upper limit of the internal RAM area, a prefetch operation (invalid
