Writing to the Control Register
Changing any of the nonvolatile bits of the control reg-
ister requires the following steps:
– Write a 02H to the Control Register to set the Write
Enable Latch (WEL). This is a volatile operation, so
there is no delay after the write. (Operation pre-
ceded by a start and ended with a stop).
– Write a 06H to the Control Register to set both the
Register Write Enable Latch (RWEL) and the WEL
bit. This is also a volatile cycle. The zeros in the data
byte are required. (Operation preceded by a start
and ended with a stop).
– Write a value to the Control Register that has all the
control bits set to the desired state. This can be repre-
sented as 0xys t 01 r in binary, where xy are the WD
bits, and rst are the BP bits. (Operation preceded by a
start and ended with a stop). Since this is a nonvola-
tile write cycle it will take up to 10ms to complete. The
RWEL bit is reset by this cycle and the sequence
must be repeated to change the nonvolatile bits
again. If bit 2 is set to ‘1’ in this third step ( 0xys t 11 r )
then the RWEL bit is set, but the WD1, WD0, BP2,
BP1 and BP0 bits remain unchanged. Writing a sec-
ond byte to the control register is not allowed. Doing
so aborts the write operation and returns a NACK.
– A read operation occurring between any of the previ-
ous operations will not interrupt the register write
operation.

– The RWEL bit cannot be reset without writing to the
nonvolatile control bits in the control register, power
cycling the device or attempting a write to a write
protected block.
To illustrate, a sequence of writes to the device con-
sisting of [02H, 06H, 02H] will reset all of the nonvola-
tile bits in the Control Register to 0. A sequence of
[02H, 06H, 06H] will leave the nonvolatile bits
unchanged and the RWEL bit remains set.
SERIAL INTERFACE
Serial Interface Conventions
The device supports a bidirectional bus oriented protocol.
The protocol defines any device that sends data onto
the bus as a transmitter, and the receiving device as the
receiver. The device controlling the transfer is called the
master and the device being controlled is called the
slave. The master always initiates data transfers, and
provides the clock for both transmit and receive opera-
tions. Therefore, the devices in this family operate as
slaves in all applications.
Serial Clock and Data
Data states on the SDA line can change only during
SCL LOW. SDA state changes during SCL HIGH are
reserved for indicating start and stop conditions. See
Figure 5.
