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.
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.
