Write timing characteristics during erase suspend are the same as write-only operations.
A write operation can be terminated with either CE# or WE#.

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.
