The CCIF flag will set after the Erase FlashBlock operation has completed.Table 45-19.

User margin read may be run using the Read 1s Block command to verify all bits are erased.45.4.10.7 Erase Flash Sector CommandThe Erase Flash Sector operation erases all addresses in a flash sector.Table 45-20. Erase Flash Sector Command FCCOB RequirementsFCCOB Number FCCOB Contents [7:0]0 0x09 (ERSSCR)1 Flash address [23:16] in the flash sector to be erased2 Flash address [15:8] in the flash sector to be erased3 Flash address [7:0]1 in the flash sector to be erased1. Must be longword aligned (flash address [1:0] = 00).After clearing CCIF to launch the Erase Flash Sector command, the flash memorymodule erases the selected program flash sector and then verifies that it is erased. TheErase Flash Sector command aborts if the selected sector is protected (see the descriptionof the FPROT registers). If the erase-verify fails the FSTAT[MGSTAT0] bit is set. TheCCIF flag is set after the Erase Flash Sector operation completes. The Erase Flash Sectorcommand is suspendable (see the FCNFG[ERSSUSP] bit and Figure 45-4).Table 45-21.
