STOP condition) following the last bit of the last Data Byte
(See Figure 18).
The Data Bytes are from the memory location indicated by
an internal pointer. This pointer initial value is determined by
the Address Byte in the Read operation instruction, and
increments by one during transmission of each Data Byte.
After reaching the memory location 01Fh (8 decimal) the
pointer “rolls over” to 00h, and the device continues to output
data for each ACK received.
The byte at address 00001000 bin (8 decimal) determines if
the Data Bytes being read are from volatile or non-volatile
memory. See “Memory Description” on page 9.
