30.4.4 Communication commands
The RL78/F13 and RL78/F14 executes serial programming through the commands listed in Table 30-7.
The signals sent from the dedicated flash memory programmer or external device to the RL78/F13 or RL78/F14 are
called commands, and programming functions corresponding to the commands are executed. For details, refer to the RL78
Microcontrollers (RL78 Protocol A) Programmer Edition Application Note (R01AN0815).
Table 30-7. Flash Memory Control Commands
Classification Command Name Function
Verify Verify
Compares the contents of a specified area of the flash memory with
data transmitted from the programmer.
Erase Block Erase Erases a specified area in the flash memory.
Blank check Block Blank Check
Checks if a specified block in the flash memory has been correctly
erased.
Write Programming Writes data to a specified area in the flash memory.
Note
Getting information Silicon Signature
Gets information from the RL78/F13 or RL78/F14 (such as the part
number, flash memory configuration, and programming firmware
version).
Checksum Gets the checksum data for a specified area.
Security Security Set Sets security information.
Security Get Gets security information.
Security Release Release setting of prohibition of writing.
Others Reset Used to detect synchronization status of communication.
Baud Rate Set Sets baud rate when UART communication mode is selected.
Note Confirm that no data has been written to the write area. Because data cannot be erased after block erase is
prohibited, do not write data if the data has not been erased.
Product information (such as product name and firmware version) can be obtained by executing the “Silicon Signature”
command.
Table 30-8 lists and describes signature data. Table 30-9 shows examples of signature data.
Table 30-8. Signature Data List
Field name Description Number of transmit data
Device code The serial number assigned to the device 3 bytes
Device name Device name (ASCII code) 10 bytes
