Notes 1. Selection items for Standard settings on GUI of the flash memory programmer.
2. Because factors other than the baud rate error, such as the signal waveform slew, also affect UART
communication, thoroughly evaluate the slew as well as the baud rate error.
27.6.4 Communication commands
The 78K0R/Lx3 microcontrollers communicate with the dedicated flash memory programmer by using commands. The
signals sent from the flash memory programmer to the 78K0R/Lx3 microcontrollers are called commands, and the signals
sent from the 78K0R/Lx3 microcontrollers to the dedicated flash memory programmer are called response.

The flash memory control commands of the 78K0R/Lx3 microcontrollers are listed in the table below. All these
commands are issued from the programmer, and the 78K0R/Lx3 microcontrollers perform processing corresponding to the
respective commands.
