8.1.5 Read operations
Read operations are initiated in the same manner as write operations with the
exception that the LSB of the slave address (R/W) is set to logic 1.
There are three basic read operations: current address read, random read, and
sequential read.
Remark: During read operations all bits of the memory address are incremented
after each transmission of a data byte. Contrary to write operations, an overflow of the
memory address occurs from 2047 to 0 (see Figure 8).
