This is a read-only bit indicating the status of auto-erasure or the block blank check command. The bit is set to
1 if an erase error or blank check error occurs; otherwise, it is set to 0. Refer to 26.5.8 Full Status Check for

• During programming
• During erasure
• During the lock bit program
• During the read lock bit status
• During the block blank check
