Zone1 : Power Management DATA, DATA_SCALE zone

Zone 1 region of the EEPROM provides the power

management registers with user values for the DATA and

DATA_SCALE fields, that will be provided to the system

software when requests are made through the

DATA_SELECT field.

Since there are 16 possible values for the DATA_SELECT

fields, the system can request up to 16 sets of DATA and

DATA_SCALE values. The organisation of the EEPROM

data for this zone is shown in the table. Each DATA and

DATA_SCALE value being programmed is relevant to a

particular value of the DATA_SELECT parameter.
