X = Don’t care.
RA = Read Address.
RD = Read Data.
PA = Address of the memory location to be programmed. Addresses
latch on the falling edge of the WE# or CE# pulse whichever
happens later.
PD = Program Data. Data latches on the rising edge of WE# or CE#
pulse, whichever occurs first.

All values are in hexadecimal.
Except for the following, all bus cycles are write cycle: read
cycle, fourth through sixth cycles of the Autoselect commands,
fourth cycle of the password verify command, and any cycle
reading at RD(0) and RD(1).
Data bits DQ15 – DQ8 are don’t care in command sequences,
except for RD, PD, WD, PWD, and PWD3 – PWD0.
Unless otherwise noted, these address bits are don’t cares:
PL127: A22 – A15; 129N: A21 – A15; PL256N: A23 – A14.
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.
The 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.
