The data output is sequential, with the data from  
address n followed by the data from n + 1. The address  
Sequential Read  
Sequential reads can be initiated as either a current  
address read or random access read. The first byte is  
counter for read operations increments all address bits,  
allowing the entire memory contents to be serially read  
transmitted as with the other modes, however, the  
master now responds with an acknowledge, indicating  
during one operation. At the end of the address space  
(address 8191), the counter “rolls over” to 0 and the  
it requires additional data. The X24645 continues to  
output data for each acknowledge received. The read  
X24645 continues to output data for each acknowledge  
received. Refer to Figure 9 for the address,  
operation is terminated by the master; by not responding  
with an acknowledge and then issuing a  
stop condition.
