... BUS CHARACTERISTICS The following bus protocol has been defined: • Data transfer may be initiated only when the bus is not busy. • During data transfer, the data line must remain stable whenever the clock line is high. Changes in the data line while the clock line is high will be interpreted as a Start or Stop condition ...

... DEVICE ADDRESSING A control byte is the first byte received following the Start condition from the master device (Figure 5-1). The control byte consists of a 4-bit control code. For the ’ 24XX128, this is set as ‘1010 binary for read and write operations ...
Page 8
... WRITE OPERATIONS 6.1 Byte Write Following the Start condition from the master, the control code (four bits), the Chip Select (three bits) and the R/W bit (which is a logic low) are clocked onto the bus by the master transmitter. This indicates to the ...
Page 9
... ACKNOWLEDGE POLLING Since the device will not acknowledge during a write cycle, this can be used to determine when the cycle is complete (This feature can be used to maximize bus throughput). Once the Stop condition for a Write command has been issued from the master, the device initiates the internally timed write cycle ...
Page 10
... READ OPERATION Read operations are initiated in much the same way as write operations with the exception that the R/W bit of the control byte is set to ‘ 1 ’. There are three basic types of read operations: current address read, random read and sequential read ...
