6.2
After generating a START condition, the processor
transmits a control byte consisting of a EEPROM
address and a Read/Write bit that indicates what type
of operation is to be performed. The EEPROM 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 6-5). The bus is monitored for its cor-
responding EEPROM address all the time. It generates
an acknowledge bit if the EEPROM address was true
and it is not in a programming mode.
