Register : Data Start Register - warmram_datastart

Description

Offset into On-chip RAM of the start of the region for CRC validation

Reset only on a cold reset.

Register Layout

Bits Access Reset Description
[31:0] RW 0x0 Data Start Offset

Field : Data Start Offset - offset

Contains the byte offset into the On-chip RAM of the start of the On-chip RAM region for the warm boot CRC validation. The offset must be an integer multiple of 4 (i.e. aligned to a word). The Boot ROM code will set the top 16 bits to 0xFFFF and clear the bottom 2 bits.

Data Structure Documentation

struct ALT_SYSMGR_ROM_WARMRAM_DATASTART_s

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.
