SCL SDA Start Condition © 2005 Microchip Technology Inc. 24AA16/24LC16B 3.4 Data Valid (D) The state of the data line represents valid data when, after a Start condition, the data line is stable for the duration of the high period of the clock signal. The data on the line must be changed during the low period of the clock signal ...

... Device Addressing A control byte is the first byte received following the Start condition from the master device (Figure 3-2). The control byte consists of a four-bit control code. For the 24XX16, this is set as ‘ 1010 and write operations. The next three bits of the control byte are the block-select bits (B2, B1, B0) ...

However, instead of generating a Stop condition, the master transmits data bytes to ...
Page 8
... 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 and ACK polling can then be initiated immediately ...

... R T SDA Line S Bus Activity © 2005 Microchip Technology Inc. 24AA16/24LC16B 7.3 Sequential Read Sequential reads are initiated in the same way as a random read, except that once the 24XX16 transmits the first data byte, the master issues an acknowledge as opposed to a Stop condition in a random read. This directs the 24XX16 to transmit the next sequentially- addressed 8-bit word (Figure 7-3) ...
