Notes:
1.
Write timing characteristics during erase suspend are the same as write-only operations.
2.
CE#- or WE#-high terminates a write operation.
3.
Sampled, not 100% tested.
4.
Write pulse width low (t_WLWH or t_ELEH) is defined from CE# or WE# low (whichever occurs last) to CE# or WE# high
(whichever occurs first). Hence, t_WLWH = t_ELEH = t_WLEH = t_ELWH.
5.
Write pulse width high (t_WHWL or t_EHEL) is defined from CE# or WE# high (whichever is first) to CE# or WE# low
(whichever is last). Hence, t_WHWL = t_EHEL = t_WHEL = t_EHWL.
6.
V_PP and WP# should be at a valid level without changing state until erase or program success is determined.
7.
This spec is only applicable when transitioning from a write cycle to an asynchronous read.
8.
When doing a read status operation following any command that alters the Status Register contents, W14 is 20ns.
9.
Add 10ns if the write operation results in a block lock status change, for subsequent read operations to reflect this change.
10.
Guaranteed by design.
