LP8580 Evaluation Board
When LP8580 is started up, EEPROM content is locked from editing. To be able to write new values in the
EEPROM, first it must be unlocked. This can be done by clicking the
Unlock button. The status of the
EEPROM lock can be checked by pressing the Read status button. If EEPROM is unlocked the EEPROM
unlocked status indicator turns red. EEPROM can be locked again by pressing the Lock button. The
Read NVM button reads the content of the LP8580 EEPROM to LP8580 control registers.
The Save button can be used to save the EEPROM settings in the EEPROM content window to a text file
for future use. To save the content of the LP8580 EEPROM to a text file, first press the Read button to
read the content of the LP8580 EEPROM into the EEPROM content window.
The Load button can be used to load EEPROM values form a text file into EEPROM content window.
EEPROM content of the LP8580 IC is not updated until the Write button is pressed.
