24AAXX/24LCXX/24FCXX
4.0
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.
