M24256, M24128
There are two modes both for read and write.
These are summarized in Table 4 and described
later. A communication between the master and
the slave is ended with a STOP condition.
Each data byte in the memory has a 16-bit (two
byte wide) address. The Most Significant Byte (Ta-
ble 5) is sent first, followed by the Least significant
Byte (Table 6). Bits b15 to b0 form the address of
the byte in memory. Bit b15 is treated as a Don’t
Care bit on the M24256 memory. Bits b15 and b14
are treated as Don’t Care bits on the M24128
memory.
