F7H EOX (End Of Exclusive)
* The amount of data that can be transmitted at one time depends on the type of
data, and data will be transmitted from the specified starting address and size.
Refer to the address and size given in “Parameter Address Map” (p. 113).
* Data larger than 256 bytes will be divided into packets of 256 bytes or less, and
each packet will be sent at an interval of about 20 ms.
* Regarding the checksum, please refer to (p. 116)
