For the following two commands, the Intel Hex format is used in part of the transfer format:
For information on the definition of the Intel Hex format, refer to Table 22-20.
Data is in binary form. The start mark ":" must be transmitted as binary data of 0x3A.

lower bytes of the checksum). (3-byte data is used if the flash memory write command is used. If the RAM

the checksum.)
