FUNCTIONAL DESCRIPTION

Each 24XX device 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 gener-

ates the Serial Clock (SCL), controls the bus access

and generates the Start and Stop conditions, while the

24XX works as slave. Both master and slave can

operate as transmitter or receiver, but the master

device determines which mode is activated.
