6.3.1 SW Reset CSR Configuration Section Length - Offset 0x0
The section length word contains the length of the section in words. Note that section length count does
not include the section length word and Block CRC8 word.
6.3.2 Block CRC8 (Offset 0x1)
6.3.3 CSR Address - (Offset 3*n - 1; [n = 1... Section Length])
6.3.4 CSR Data LSB - (Offset 3*n; [n = 1... Section Length])
6.3.5 CSR Data MSB - (Offset 3*n + 1; [n = 1... Section Length])
6.4 PCIe Reset CSR Auto Configuration Pointer (LAN Base
Address + Offset 0x23)
This word points to the PCIe Reset CSR auto configuration structure of the LAN that is read only
following power-up or PCIe reset. Sections are loaded during HW auto-load as described in
Section 3.3.1.2. If no CSR autoload is required, the word must be set to 0xFFFF.
The PCIe Reset CSR Auto Configuration structure format is listed in the following tables.
