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.
Remark:
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.
Fig 7.
Master reads PCF8598C-2 slave after setting word address (write word address; read data);
sequential read.
