EEPROM Loader
The EEPROM Loader interfaces to the I
CSRs (via the Register Access MUX). Only system CSRs at addresses 100h and above are accessible
to the EEPROM Loader (with the addition of the
(PMI_DATA)
A8 respectively).
The EEPROM Loader runs upon a pin reset (nRST), power-on reset (POR), digital reset
(DIGITAL_RST bit in the
command via the
Loader, but only the MAC address is loaded into the Host MAC. Refer to
page 36
The EEPROM contents must be loaded in a specific format for use with the EEPROM Loader. An
overview of the EEPROM content format is shown in
