3669 | ......\r | |

3680 | (Block1 and Block2 has overlap region, merge the overlap value to Block1 and Blcok2)\r | |
3681 | \r | |
3682 | Block1 and Block2 have overlap byte region, but currntly the default value of Block1 only contains\r | |
3683 | value of Bit1 (low 6 bits),the default value of Block2 only contains the value of Bit2 (middle 5 bits).\r | |
3684 | \r | |
3685 | This fuction merge the default value of these two blocks, and make the default value of block1\r | |
