FUNCTIONAL DESCRIPTION
3.4
Data Valid (D)
The 24XX16H supports a bidirectional, 2-wire bus and
data transmission protocol. A device that sends data
onto the bus is defined as a transmitter, while a device
receiving data is defined as a receiver. The bus has to
be controlled by a master device which generates the
Serial Clock (SCL), controls the bus access and
generates the Start and Stop conditions, while the
24XX16H 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
bit of data.
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 and is
