8.9.2. Write methods for data transfer
1) Single-byte write method
The first data write method transfers each byte of data independently.
The target address for writing is specified by the address pointer and "8h" is written to the transfer format
register.
After one byte of data has been transferred, the transfer can be terminated by setting the CE pin to low level,
or the transfer operation can be continued by specifying a new target address and transfer format.

2) Burst write method
The second data write method transfers data consecutively.
The target address for writing is specified by the address pointer and "0h" is written to the transfer format
register.
The address pointer is incremented each time a byte is transferred. The next address pointer value after Fh is
0h.
Lastly, the transfer is terminated by setting the CE pin to low level.
