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/JG3-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
Recommended use of address space
(invalid fetch) straddling the on-chip peripheral I/O area does not occur.
