(6) Continuous write operation

This IC possesses a function which can write data continuously. With the continuous write operation, write data

is written in a manner similar to the byte write operation. Continuous write is possible by sending write data

continuously before sending "Stop". The address used to write data during the continuous write operation is

automatically incremented when each separate write operation terminates.

There is no limit on the number of continuous transfers that are possible to write continuously with this IC.

(7) Byte read operation

After "Start" is sent, the R/W code is set to low and an 8-bit device address word is input. The IC outputs

"Acknowledgment" to the 9th bit and enters write mode. After this, "Acknowledgment" is output every 8 bits

after each of the two 8-bit memory addresses are input. Once the addresses are acknowledgment, "Restart" is

input, and the R/W code is set to high, an 8-bit device address word is input, and the IC outputs

"Acknowledgment" to the 9th bit and enters read mode. Next, 8 bits of read data are output using the address

used for the dummy write, and the read operation terminates if "Stop" is input without inputting

"Acknowledgment".
