Figure 9. Write Modes Sequence with Write Control = 1

sequence. To terminate the stream of bytes, the

master must NOT acknowledge the last byte out-

put, but MUST generate a STOP condition. The

output data is from consecutive byte addresses,

with the internal byte address counter automat-

ically incremented after each byte output. After a

count of the last memory address, the address

counter will ’roll-over’ and the memory will continue

to output data.

Acknowledge in Read Mode. In all read modes

the ST24/25E64 wait for an acknowledge during

the 9th bit time. If the master does not pull the SDA

line low during this time, the ST24/25E64 terminate

the data transfer and switch to a standby state.
