The following error indications are possible for Read operations:
In addition to data reads, users can read the status of any page in the FB by asserting PAGESTATUS
along with REN. The format of the data returned by a page status read is shown in

Read Protected; read protect bit for page, which is set via the JTAG interface and
only affects JTAG operations. This bit can be overridden by using the correct user
key value.
Write Protected; write protect bit for page, which is set via the JTAG interface and
only affects JTAG operations. This bit can be overridden by using the correct user
key value.
Overwrite Protected; designates that the user has set the OVERWRITEPROTECT
bit on the interface while doing a Program operation. The page cannot be written
without first performing an Unprotect Page operation.
