Notes 1. Address differs depending on products as follows.
Address of Note 1 Products (code flash memory capacity)
R5F10ExA (x = 8, B, G) 03FFFH
R5F10ExC (x = 8, B, G, L) 07FFFH
R5F10ExD (x = 8, B, G, L) 0BFFFH
R5F10ExE (x = 8, B, G, L) 0FFFFH
2. When real-time RAM monitor (RRM) function and dynamic memory modification (DMM) function are not
used, it is 256 bytes.
3. In debugging, reset vector is rewritten to address allocated to a monitor program.
4. Since this area is allocated immediately before the stack area, the address of this area varies depending on
the stack increase and decrease. That is, 4 extra bytes are consumed for the stack area used.
When using self-programming, 12 extra bytes are consumed for the stack area used.
