Data Flash Access and Format
18.1 Data Flash Access
18.1.1 Minimum Voltage
Data flash can only be updated when the sum of the cell voltages connected between the VC0 and VC5
pins of the companion AFE is above the Valid Update Voltage.
Class Subclass Name Type Min Max Default Unit Description

I2 0 32767 3500 mV
Min voltage threshold for Flash update
NOTE:
• VC1 to VC5 voltages may not be represented directly by CellVoltage1...5() when the
number of cells in series is > 5. The VCx to CellVoltagex() decode is through the
DF:AFE Cell Map.
• It is not recommended to change this value.
18.2 Data Formats
18.2.1 Unsigned Integer (U)
Unsigned integer is stored without changes as 1-byte, 2-byte, or 4-byte values in Little Endian byte order.
