Figure 10-2. Read Zone
Note:
The data byte address is internally incremented following the transmission of each data byte. As
long as the AT88SC1608 receives an acknowledge from the host, it will continue to increment
the data byte address and serially clock out sequential data bytes. During a read operation, the
address will “roll over” 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 data byte
with all bits equal to “0”.
Figure 10-3. Write Zone
Note:
The lower four bits of the data byte address are internally incremented following the receipt of
each data byte. The higher data byte address bits are not incremented, retaining the 16-byte
write-page address. Each data byte within a page must only be loaded once. Once a stop condi-
tion is issued to indicate the end of the host’s write command, the device initiates the internally
timed nonvolatile write cycle. An ACK polling sequence can be initiated immediately. After a
write command, if the host is not allowed to write to some address locations, a nonvolatile write
cycle will still be initiated. However, the device will only modify data at the allowed addresses.
