69 / 334 page  Fusion Family of Mixed Signal FPGAs Revision 4 2-53 Unprotect Page Operation An Unprotect Page operation will clear the protection for a page addressed on the ADDR input. It is initiated by setting the UNPROTECTPAGE signal on the interface along with the page address on ADDR. If the page is not in the Page Buffer, the Unprotect Page operation will copy the page into the Page Buffer. The Copy Page operation occurs only if the current page in the Page Buffer is not Page Loss Protected. The waveform for an Unprotect Page operation is shown in Figure 2-42. The Unprotect Page operation can incur the following error conditions: 1. If the copy of the page to the Page Buffer determines that the page has a single-bit correctable error in the data, it will report a STATUS = '01'. 2. If the address on ADDR does not match the address of the Page Buffer, PAGELOSSPROTECT is asserted, and the Page Buffer has been modified, then STATUS = '11' and the addressed page is not loaded into the Page Buffer. 3. If the copy of the page to the Page Buffer determines that at least one block in the page has a double-bit uncorrectable error, STATUS = '10' and the Page Buffer will contain the corrupted data. Discard Page Operation If the contents of the modified Page Buffer have to be discarded, the DISCARDPAGE signal should be asserted. This command results in the Page Buffer being marked as unmodified. The timing for the operation is shown in Figure 2-43. The BUSY signal will remain asserted until the operation has completed.
