SEQUENTIAL READ: Sequential reads are initiated by either a current address read or a random address read. After the
microcontroller receives a data word, it responds with an acknowledge. As long as the EEPROM receives an acknowledge,
it will continue to increment the data word address and serially clock out sequential data words. When the memory
address limit is reached, the data word address will “roll over” and the sequential read will continue. The sequential read
operation is terminated when the microcontroller does not respond with a zero but does generate a following stop
condition (see Figure 8-6 on page 13 ).
PERMANENT WRITE PROTECT REGISTER (PSWP) STATUS: To find out if the register has been programmed,
the same procedure is used as to program the register except that the R/W bit is set to one. If the device sends
an acknowledge, then the permanent write protect register has not been programmed. Otherwise, it has been
programmed and the device is permanently write protected at the first half of the array.

REVERSIBLE WRITE PROTECT REGISTER(RSWP) STATUS: To find out if the register has been programmed,
the same procedure is used as to program the register except that the R/W bit is set to one. If the sends an
device acknowledge, then the reversible write protect register has not been programmed. Otherwise, it has
been programmed and the device is write protected (reversible) at the first half of the array.
