■ COMMAND

• Byte Write

If the device address word (R/W “0” input) is sent after the start condition, an ACK responds from the slave.

After this ACK, write memory addresses and write data are sent in the same way, and the write ends by

generating a stop condition at the end.

• Page Write

If data is continuously sent after the following address when the same command (expect stop condition) as

Byte Write was sent, a page write is performed. The memory address rolls over to first memory address

starting from the start of the memory address that was written first.
