5.2.8 EEPROM Initialization
This section describes how to initialize the EEPROM, what kind of parameter will be
initialized, and what's for. This operation must be made only when you replace to new
main board.
NOTE: Even though you perform the EEPROM initialization, it does not mean
all parameters in EEPROM will be initialized, and USB ID that you
registered in Section 5.2.7 will never be changed and cleared.
†
Purpose
There are some important parameters in EEPROM and the firmware compares/
checks its data at power on timing. So, if the parameters have been changed caused
by some unexpected causes, unexpected error indication may possibly be
occurred. To prevent such this problem, the adjustment program has a function to
overwrite the important factory setting parameters onto an each specific EEPROM
address.
†
What kind of parameter will be initialized by this operation
Followings are the all items that EEPROM initialization supports.
