Read operations
The read operations are initiated in the same way 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 eight 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.
