Notes 1. Address differs depending on products as follows.
Products (code flash memory capacity) Address of Note 1
R5F100xA, R5F101xA (x = 6 to 8, A to C, E to G) 03FFFH
R5F100xC, R5F101xC (x = 6 to 8, A to C, E to G, J, L) 07FFFH
R5F100xD, R5F101xD (x = 6 to 8, A to C, E to G, J, L) 0BFFFH
R5F100xE, R5F101xE (x = 6 to 8, A to C, E to G, J, L) 0FFFFH
R5F100xF, R5F101xF (x = A to C, E to G, J, L, M, P) 17FFFH
R5F100xG, R5F101xG (x = A to C, E to G, J, L, M, P) 1FFFFH
R5F100xH, R5F101xH (x = E to G, J, L, M, P, S) 2FFFFH
R5F100xJ, R5F101xJ (x = F, G, J, L, M, P, S) 3FFFFH
R5F100xK, R5F101xK (x = F, G, J, L, M, P, S) 5FFFFH
R5F100xL, R5F101xL (x = F, G, J, L, M, P, S) 7FFFFH
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.
