DEVICE ADDRESSING

After generating a Start condition, the bus master

transmits a control byte consisting of a slave address

and a Read/Write bit that indicates what type of

operation is to be performed. The slave address for the

24XX00 consists of a 4-bit device code ‘1010’ followed

by three “don’t care” bits.

The last bit of the control byte determines the operation

to be performed. When set to a one a read operation is

selected, and when set to a zero a write operation is

selected (Figure 5-1). The 24XX00 monitors the bus for

its corresponding slave address all the time. It

generates an Acknowledge bit if the slave address was

true and it is not in a programming mode.
