6.4.5 CSR Data MSB - (Offset 3*n + 1; [n = 1... Section Length])
6.5 CSR Auto Configuration Power-Up Pointer (Offset 0x27)
This word points to the CSR auto configuration power-up structure of the LAN that is read only following
power up. 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 CSR Auto Configuration Power-Up structure format is listed in the following tables.
6.5.1 CSR Configuration Power-Up 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.
6.5.2 Block CRC8 (Offset 0x1)
