Note The RAM in the R5F10266 has capacity as small as 256 bytes. Depending on the customer's program
specification, the stack area to execute the data flash library may not be kept and data may not be written to or
erased from the data flash memory.
Caution When the flash memory is rewritten via a user program, the code flash area and RAM area are used
because each library is used. When using the library, refer to RL78 Family Flash Self Programming Library
Type01 User's Manual and RL78 Family Data Flash Library Type04 User's Manual.
