After a START condition, the master always transmits a Command Byte CSW or CSR.
After the acknowledge of the EEPROM a Control Byte follows, its content and the
transmitter depend on the previous Command Byte. The description of the Command
and Control Bytes is shown in
table 2
.
Device Addressing and EEPROM Addressing
The device has an internal address counter which points to the current EEPROM
address.
The address counter is incremented
– after a data byte to be written has been acknowledged, during entry of further data
byte
– during a byte read, thus the address counter points to the following address after
reading a data byte.
Command Byte
Selects operation:
the least significant bit b0 is low for a write
operation (Chip Select Write Command Byte CSW) or set high for a
read operation (Chip Select Read Command Byte CSR).
Contains address information:
in the CSW Command Byte, the
bit positions b2 or b3 to b1 are decoded for the two or three
uppermost EEPROM address bits A9 or A10 to A8 (in the CSR
Command Byte, the bit positions b3 to b1 are left undefined).
Following CSW (b0 = 0):
contains the eight lower bits of the
EEPROM address (EEA) bit A7 to A0, or an additional command
byte for the handling of the protection bit.
Following CSR (b0 = 1):
contains the data read out, transmitted by
the EEPROM. The EEPROM data are read as long as the master
pulls down SDA after each byte in order to acknowledge the
transfer. The read operation is stopped by the master by releasing
SDA (no acknowledge is applied) followed by a STOP condition.
