yte of the first p

ge. The
a
ddress “roll over” during write is from the l
a
st
b
yte of the current
p
a
ge to the first
b
yte of the s
a
me p
a
ge.
Once the device
a
ddress with the re
a
d/write select
b
it set to one is clocked in
a
nd
a
cknowl-
edged
b
y the EEPROM, the current
a
ddress d
a
t
a
word is seri
a
lly clocked out. The
microcontroller does not respond with
a
n input zero
b
ut does gener
a
te
a
following stop condi-
tion (see Figure 10 on p
a
ge 11).
RANDOM READ:
A r
a
ndom re
a
d requires
a
“dummy”
b
yte write sequence to lo
a
d in the d
a
t
a
word

ddress. Once the device

ddress word

t
a
word
a
ddress
a
re clocked in
a
nd
a
cknowledged
b
y the EEPROM, the microcontroller must gener
a
te
a
nother st
a
rt condition.
The microcontroller now initi

current

ddress re

d
b
y sending
a
device
a
ddress with the
re
a
d/write select
b
it high. The EEPROM
a
cknowledges the device
a
ddress
a
nd seri
a
lly clocks
out the d
a
t
a
word. The microcontroller does not respond with
a
zero
b
ut does gener
a
te
a
fol-
lowing stop condition (see Figure 11 on p

SEQUENTIAL READ:

y either
a
current
a
ddress re

d or

r
a
n-
dom
a
ddress re
a
d. After the microcontroller receives
a
d
a
t
a
word, it responds with
a
n
a
cknowledge. As long
a
s the EEPROM receives
a
n
a
cknowledge, it will continue to increment
the d
a
t
a
word
a
ddress
a
nd seri
a
lly clock out sequenti
a
l d

words. When the memory
a
ddress limit is re
a
ched, the d
a
t

word
a
ddress will “roll over”
a
nd the sequenti
a
l re

d will con-
tinue. The sequenti
a
l re
a
d oper
a
tion is termin
a
ted when the microcontroller does not respond
with
a
zero
b
ut does gener
a

a
following stop condition (see Figure 12 on p
