in and acknowledged by the EEPROM, the microcontroller must generate another start
condition. The microcontroller now initiates a current address read by sending a device
address with the read/write select bit high. The EEPROM acknowledges the device
address and serially clocks out the data word. To end the command, the microcontroller
does not respond with a zero but does generate a following stop condition (see Figure
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 sequen-
tial read will continue. The sequential read operation is terminated when the
microcontroller does not respond with a zero but does generate a following stop condi-
tion (see Figure 13 on page 13).
WRITE PROTECT REGISTER STATUS: To find out if the register has been pro-
grammed, the same procedure is used as to program the register except that the R/W
bit is set to 1. If the device acknowledges, then the 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.
