Current Address Read

The EEPROM content is read without setting an EEPROM address, in this case the

current content of the address counter will be used (e.g. to continue a previous read

operation after the Master has served an interrupt).

Current Address Read

Transmission of CSR

For a current address read the master generates a START

condition, which is followed by the command byte CSR (chip

select read). The receipt of the CSR-byte is acknowledged by

the EEPROM with a low on the SDA line.

Transmission of

EEPROM Data

During the next eight clock pulses the EEPROM transmits the

data byte and increments the internal address counter.

STOP Condition from

Master

During the following clock cycle the masters releases the bus

and then transmits the STOP condition.
