The data output is sequential, with the data
from address n followed by the data from
n + 1. The address counter for Read
operations increments all word address
bits, enabling the entire memory contents
to be serially read during one operation.
After the entire memory has been read, the
counter rolls over to the beginning of the
memory. The SA24C1024 continues to
output data for each ACK received. For
details regarding the address,
acknowledge, and data transfer sequence,
see Figure 17.
