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.
8.5.1
R
EMARK
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 Fig.3).
Fig.7 Master reads PCx85116-3 slave after setting word address (write word address; read data).
