RL78/G1A CHAPTER 25 FLASH MEMORY
The following methods for programming the flash memory are available.
The code flash memory can be rewritten to through serial programming using a flash memory programmer or an
external device (UART communication), or through self-programming.
<R>
• Serial programming using flash memory programmer (see 25.4)
Data can be written to the flash memory on-board or off-board by using a dedicated flash memory programmer.
• Serial programming using external device (UART communication) (see 25.2)
Data can be written to the flash memory on-board through UART communication with an external device
(microcontroller or ASIC).
• Self-programming (see 25.6)
The user application can execute self-programming of the code flash memory by using the flash self-programming
library.
The data flash memory can be rewritten to by using the data flash library during user program execution (background
operation). For access and writing to the data flash memory, see 25.8 Data Flash.
