Figure 3-1. Memory Map (R5F10AmA (m = 6, A, B, G))
Notes 1. Do not allocate RAM addresses which are used as stack area, data buffers used by the libraries, branch
destinations for vectored interrupt servicing, or DTC transfer destinations/transfer sources to the area FFE20H
to FFEDFH when performing self-programming and rewriting the data flash memory.
2. Instructions can be executed from the RAM area excluding the general-purpose register area.
3. When boot swap is not used: Set the option bytes to 000C0H to 000C3H, and the on-chip debug security IDs
to 000C4H to 000CDH.
When boot swap is used: Set the option bytes to 000C0H to 000C3H and 020C0H to 020C3H, and the on-
chip debug security IDs to 000C4H to 000CDH and 020C4H to 020CDH.
4. Writing boot cluster 0 can be prohibited depending on the setting of security (see 30.6 Security Settings).
Caution When executing instructions from the RAM area, be sure to initialize the used RAM area + 10 bytes
with any desired value.
