DEVICE COMMANDS
Device operations are initiated by writing desig-
nated address and data
command sequences
into
the device. A command sequence is composed
of one, two or three of the following sub-segments:
an
unlock cycle
, a
command cycle
and a
data
cycle
. Table 4 summarizes the composition of the
valid command sequences implemented in the
HY29F002T, and these sequences are fully de-
scribed in Table 5 and in the sections that follow.
Writing incorrect address and data values or writ-
ing them in the improper sequence resets the
HY29F002T to the Read mode.
Read/Reset 1, 2 Commands
The HY29F002T automatically enters the Read
mode after device power-up, after the RESET#
input is asserted and upon the completion of cer-
tain commands. Read/Reset commands are not
required to retrieve data in these cases.
