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 con-
tinue. The sequential read operation is terminated when
the microcontroller does not respond with a zero but does
generate a following stop condition (refer to Figure 7).
WRITE PROTECT REGISTER 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 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.
