      Currently evaluating this FLASH and attempting to lock registers using the WP# pin, however it's not working as advertised.

      Using the WRR command I am able to set SRNV-1[SRWD]=1, which now should  follow WP#. I power cycle  and can verify

      that  it is  set via UBOOT console using RDSR-1.


      What I expect to happen is that if I ground WP# I should NOT be able to change SRNV1, however I am able to toggle this

      register even with the pin grounded. What  am I missing? Thanks in advance.
