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.
