After the last memory address, the address

counter will ‘roll-over’ and the memory will contin-

ue to output data from the start of the memory

block.

Acknowledge in Read Mode

In all read modes the memory waits for an ac-

knowledgment during the 9th bit time. If the master

does not pull the SDA line low during this time, the

memory terminates the data transfer and switches

to its standby state.

Note: 1. The seven most significant bits of the Device Select bytes of a Random Read (in the 1st and 3rd bytes) must be identical.
