In the case of writing, if 256 bytes data must be written, data must be written eight times separately since
maximum number of addresses can be written at once is 32 addresses.
[SLV]:
[START_H] x 16 + [START_L]:
[END_H] x 16 + [END_L]:
[Data (i)]:
[DataLenH]:
[DataLenL]:
The format for reading from IC on camera
・Sending data
02, 4A, 00, 05, [SLV], [START_H], [START_L], [END_H], [END_L], [CHK], 03
・Receiving data
02, 4A, [DataLenH], [DataLenL], [SLV], [START_H], [START_L], [END_H], [END_L], [DATA (START)],
[DATA (START + 1)], ... , [DATA (END)], [CHK], 03
