Functional Description
Start Condition
A high-to-low transition of the SDA with the SCL high is needed in order to start read, write operation.
(See start condition and stop condition)
Stop Condition
A low-to-high transition of the SDA with the SCL high is a stop condition. The stand-by operation starts
after a read sequence by a stop condition. In the case of write operation, a stop condition terminates the
write data inputs and place the device in a internally-timed write cycle to the memories. After the
internally-timed write cycle which is specified as t
WC
, the device enters a standby mode. (See write cycle
timing)

Acknowledge
All addresses and data words are serially transmitted to and from in 8-bit words. The receiver sends a zero
to acknowledge that it has received each word. This happens during ninth clock cycle. The transmitter
keeps bus open to receive acknowledgment from the receiver at the ninth clock. In the write operation,
EEPROM sends a zero to acknowledge after receiving every 8-bit words. In the read operation, EEPROM
sends a zero to acknowledge after receiving the device address word. After sending read data, the
EEPROM waits acknowledgment by keeping bus open. If the EEPROM receives zero as an acknowledge,
it sends read data of next address. If the EEPROM receives acknowledgment "1" (no acknowledgment) and
a following stop condition, it stops the read operation and enters a stand-by mode. If the EEPROM
receives neither acknowledgment "0" nor a stop condition, the EEPROM keeps bus open without sending
read data.
