Hi,
 
When I use s26kl512s hyperflash model, i meet some problem about read status regiset command.
 
I send write buffer program first, as shown in the picture below:
 
[ write buffer program ]

Then I send write buffer program confirm command, as below:

I want to know when program done, so I send read status register CMD as below:

However, there are neither RWDS signal nor valid register value in the wave.

I also have a question:  Is read latency setting  also applied to read status register command  or not?
