FIGURE 7-4:
7.2
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 opera-
tion is to be performed. The slave address 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 7-5). The bus is monitored for its cor-
responding slave address all the time. It generates an
acknowledge bit if the slave address was true and it is
not in a programming mode.
