Legend:
X = Don’t care.
RA = Read Address.
RD = Read Data.
PA = Program Address. Addresses latch on the rising edge of the
AVD# pulse or active edge of CLK, whichever occurs first.
PD = Program Data. Data latches on the rising edge of WE# or CE#
pulse, whichever occurs first.

All values are in hexadecimal.
Shaded cells indicate read cycles.
Address and data bits not specified in table, legend, or notes are
don’t cares (each hex digit implies 4 bits of data).
Writing incorrect address and data values or writing them in the
improper sequence may place the device in an unknown state.
The system must write the reset command to return the device
to reading array data.
No unlock or command cycles required when bank is reading
array data.
Reset command is required to return to reading array data (or to
the erase-suspend-read mode if previously in Erase Suspend)
when a bank is in the autoselect mode, or if DQ5 goes high
(while the bank is providing status information) or performing
sector lock/unlock.
The system must provide the bank address. See
section for more information.
Data in cycle 5 is 2230 (WS256N) or 2231 (WS128N).
