USER_DATA Bits 31 : 0
R/W
0xffffff
All of the user data in one page is stored in NDFC_USER_DATA_N.
The start register address of each ECC DATA BLOCK's user data is determined by
its length configured in NDFC_USER_DATA_LEN_N.
For example:
ECC DATA BLOCK[0] user data len = 8 bytes, address = 0x80
ECC DATA BLOCK[1] user data len = 0 byte,
ECC DATA BLOCK[2] user data len = 4 bytes, address = 0x80+8
ECC DATA BLOCK[3] user data len = 4 bytes, address = 0x80+8+4
ECC DATA BLOCK[4] user data len = 0 byte
ECC DATA BLOCK[5] user data len = 16 bytes, address = 0x80+8+4+4
ECC DATA BLOCK[6] user data len = 0 byte
ECC DATA BLOCK[7] user data len = 0 byte
