24C32A  
Following the start condition, the 24C32A monitors the  
SDA bus checking the device type identifier being  
transmitted. Upon receiving a 1010 code and appropri-  
ate device select bits, the slave device outputs an  
acknowledge signal on the SDA line. Depending on the  
state of the R/W bit, the 24C32A will select a read or  
write operation.  
3.6  
Device Addressing  
A control byte is the first byte received following the  
start condition from the master device. The control byte  
consists of a 4-bit control code; for the 24C32A this is  
set as 1010 binary for read and write (R/W) operations.  
The next three bits of the control byte are the device  
select bits (A2, A1, A0). They are used by the master  
device to select which of the eight devices are to be  
accessed. These bits are in effect the three most signif-  
icant bits of the word address. The last bit of the control  
byte defines 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. The next two bytes  
received define the address of the first data byte  
(Figure 3-3). Because only A11...A0 are used, the  
upper four address bits must be zeros. The most signif-  
icant bit of the most significant byte of the address is  
transferred first.
