MEMORY SPACE
Configuration of the memory space
The memory space consists of a data memory space and an instruction memory space. The I/O, ARAM,
BRAM, TABLE, and ERAM (external memory) areas are allocated in the data memory space, while the
instruction memory is allocated in the program memory space. The I/O, TABLE, ERAM (external memory),
ARAM and BRAM areas in the data memory space are, however, assigned a particular data bus. The memory
for any two areas can, therefore, be accessed concurrently during one cycle. What memory is accessed is
determined automatically by an address value.
Addresses allocated for the memories, and their maximum size are determined as follows. Select a memory
size to be allocated in this range.
Memory space mode
You can select a method for allocating the data memory space and the program memory space by operating
mode. Determine operating mode by mode pins (MOD2, MOD1 and MOD0) as follows.
Memory map for single chip mode
The program for single chip mode (MOD2: 0 = “000”) is operated by the internal program RAM (which externally
downloads a program). Five areas for I/O, ARAM, BRAM, TABLE and ERAM are allocated on the data memory
space, with the instruction memory allocated on a program memory space completely different from the data
memory space. Although the instruction memory can have an independent address space for 64 kwords,
therefore, you cannot access data in the instruction memory using a program.
