Length of region in On-chip RAM for CRC validation.
Reset only on a cold reset.

Bits | Access | Reset | Description |
---|---|---|---|
[31:0] | RW | 0x0 | Size |
Field : Size - size | |
Contains the length (in bytes) of the region in the On-chip RAM for the warm boot CRC validation. If the length is 0, the Boot ROM won't perform CRC calculation and CRC check to avoid overhead caused by CRC validation. If the START + LENGTH exceeds the maximum offset into the On-chip RAM, the Boot ROM won't boot from the On-chip RAM. The length must be an integer multiple of 4. The Boot ROM code will clear the top 16 bits and the bottom 2 bits. 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.
