3.4.3.2.1.1 EEPROM Analog Configuration – Section Length
The section length word contains the length of the section in words. Note that the sections length does
not contain the section length word itself.
3.4.3.2.1.2 EEPROM Analog Configuration – Data Word
Each word in the analog configuration section has the same structure: bits 7:0 are the register data and
bits 15:8 are the registers address. The analog registers are eight bits wide with an 8-bit address width.
After reading the EEPROM word, the register specified in bits 15:8 is loaded with the data from bits 7:0.
3.4.3.2.2 PCIe Analog Pointer – Word 0x03
These sections are loaded only after PE_RST_N. These sections contain the analog default
configurations for 82598's analog parts. Word 0x3 is the pointer for this section (The exact EEPROM
address, in words).
The structure of this section is listed in the following table:
