Read operations
Read operations are initiated in the same manner as write
operations with the exception that the LSB of the slave
address is set to logic 1.
There are three basic read operations; current address
read, random read and sequential read sequential read.
8.5.1
R
EMARK
The lower 8 bits of the word address are incremented after
each transmission of a data byte (read or write). The MSB
of the word address, which is defined in the slave address,
is not changed when the word address count overflows.
Thus, the word address overflows from 255 to 0 and from
511 to 256.
