(3) Acknowledgment

Acknowledgment is used to indicate whether or not data has been sent/received normally. The

"Acknowledgment" of a data transfer is performed after that data transfer when the sender releases the bus on

the 9th clock of HSCL and the receiver drives low. If the host is the receiver, the IC is informed by the host that

data has ended by the fact that "Acknowledgment" is not generated for the last data sent from the IC.

(4) Slave address specification

After "Start" is sent, a 7-bit slave address and 1-bit read/write code is sent. Read/write operations with this IC

start if the input slave address matches the device address set using HSEL. If the device address does not

match, "Acknowledgment" is not generated and the system does nothing.

(5) Byte write 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" on 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. Next, "Acknowledgment" is output after 8 bits of write

data is input and written to the IC.
