Bits | Access | Reset | Description |
---|---|---|---|
[5:0] | RW | 0x0 | ALT_NAND_CFG_SPARE_AREA_SKIP_BYTES_VALUE |
[31:6] | ??? | Unknown | UNDEFINED |
Field : value | |
Number of bytes to skip from start of spare area before last ECC sector data starts. The bytes will be written with the value programmed in the spare_area_marker register. This register could be potentially used to preserve the bad block marker in the spare area by marking it good. The default value is zero which means no bytes will be skipped and last ECC sector will start from the beginning of spare area. This value should be an even number. Field Access Macros: | |

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
