FUNCTIONAL DESCRIPTION
3.3
Stop Data Transfer (C)
The 24XX65 supports a bidirectional two-wire bus and
data transmission protocol. A device that sends data
onto the bus is defined as transmitter, and a device
receiving data as receiver. The bus must be controlled

(SCL) is high determines a Stop condition. All
operations must be ended with a Stop condition.

(SCL), controls the bus access and generates the Start
and Stop conditions, while the 24XX65 works as slave.
Both master and slave can operate as transmitter or
receiver, but the master device determines which mode
is activated.
The state of the data line represents valid data when,
after a Start condition, the data line is stable for the
duration of the high period of the clock signal.
The data on the line must be changed during the low
period of the clock signal. There is one clock pulse per

The following bus protocol has been defined:
? Data transfer may be initiated only when the bus
is not busy.
? During data transfer, the data line must remain
Each data transfer is initiated with a Start condition and
terminated with a Stop condition. The number of the
data bytes transferred between the Start and Stop
conditions is determined by the master device.

the data line while the clock line is high will be
interpreted as a Start or Stop condition.
Accordingly, the following bus conditions have been
defined (Figure 3-1).
Each receiving device, when addressed, is obliged to
generate an acknowledge after the reception of each
byte. The master device must generate an extra clock
pulse which is associated with this Acknowledge bit.

that the SDA line is stable low during the high period of
the acknowledge related clock pulse. Of course, setup
and hold times must be taken into account. During
reads, a master must signal an end of data to the slave
by NOT generating an Acknowledge bit on the last byte
that has been clocked out of the slave. In this case, the
slave (24XX65) must leave the data line high to enable
the master to generate the Stop condition.
