Figure 9-1.
Note:
The data byte address is internally incremented following the transmission of each data byte.
During a read operation, the address “roll over” is from the last byte of the current zone to the
first byte of the same zone. If the host is not allowed to read at the specified address, the device
will transmit the corresponding data byte with all bits equal to “0”.
Figure 9-2.
Note:
The data byte address lower three bits are internally incremented following the receipt of each
data byte. The higher data byte address bits are not incremented, retaining the 8-byte write page
address. Each data byte within a page must only be loaded once. Once a stop condition is
issued to indicate the end of the host’s write operation, the device initiates the internal nonvola-
tile write cycle. An ACK polling sequence can be initiated immediately. After a write command, if
the host is not allowed to write at some address locations, a nonvolatile write cycle will still be ini-
tiated, but the device will only modify data at the allowed addresses. When write lock mode is
enabled (WLM = “0”), the write cycle is initiated automatically after the first data byte has been
transmitted.
