23.6.3 Selecting communication mode
Notes 1. Selection items for Standard settings on GUI of the flash memory programmer.
23.6.4 Communication commands
sent from the flash memory programmer to the 78K0R/KE3 are called commands, and the signals sent from the
78K0R/KE3 to the dedicated flash memory programmer are called response.
issued from the programmer and the 78K0R/KE3 perform processing corresponding to the respective commands.

Communication mode of the 78K0R/KE3 is as follows.
The 78K0R/KE3 communicates with the dedicated flash memory programmer by using commands. The signals
The flash memory control commands of the 78K0R/KE3 are listed in the table below. All these commands are
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.
