•ERASE_BLK_EN
The ERASE_BLK_EN defines the granularity of the unit size of the data to be erased. The erase operation can erase either one or multiple units of WRITE_BL_LEN or one or multiple units (orsectors) of SECTOR_SIZE (see definition below).
If ERASE_BLK_EN = ’0’, the host can erase one or multiple units of SECTOR_SIZE. The erase will start from the beginning of the sector that contains the start address to the end of the sector that contains the end address. For example, if SECTOR_SIZE=31 and the host sets the Erase Start Address to 5 and the Erase End Address to 40.
If ERASE_BLK_EN = ’1’ the host can erase one or multiple units of 512 bytes. All blocks that contain data from start address to end address are erased. For example, if the host sets the Erase Start Address to 5 and the Erase End Address to 40.
