Write timing characteristics during erase suspend are the same as write-only operations.
A write operation can be terminated with either CE# or WE#.
Sampled, not 100% tested.
Write pulse width low (t

Write pulse width high (t

This specification is only applicable when transitioning from a write cycle to an asynchronous read. See spec W19 and
W20 for synchronous read.
When doing a Read Status operation following any command that alters the Status Register, W14 is 20 ns.
Add 10 ns if the write operations results in a RCR or block lock status change, for the subsequent read operation to
reflect this change.
These specs are required only when the device is in a synchronous mode and clock is active during address setup
phase.
