Table of Contents

The RL78/G1P incorporates the flash memory to which a program can be written, erased, and overwritten while

mounted on the board. The flash memory includes the "code flash memory", in which programs can be executed, and the

"data flash memory", an area for storing data.

The following three methods for programming the flash memory are available:

 Writing to flash memory by using flash memory programmer (see 23.1)

Data can be written to the flash memory on-board or off-board by using a dedicated flash memory programmer.

 Writing to flash memory by using external device (that Incorporates UART) (see 23.2)

Data can be written to the flash memory on-board through UART communication with an external device

(microcontroller or ASIC).

 Self-programming (see 23.7)

The user application can execute self-programming of the code flash memory by using the flash self-programming
