#
Write timing characteristics during erase suspend are the same as during write-only operations.
A write operation can be terminated with either CE# or WE#.
Sampled, not 100% tested.
Write pulse width low (t
(whichever occurs first). Hence, t
Write pulse width high (t
(whichever is last). Hence, t
System designers must take this into account, and can insert a software No-Op instruction to delay the first read after
issuing a command.
For commands other than resume commands.
V
Applicable during asynchronous reads following a write.

first).
