EEPROM PROGRAMMING
The following sections describe the function of each EEPROM location and how the data is to be stored.
FUNDAMENTAL PARAMETERS
Sense Resistor Value
Two factors are used to scale the current-related measurements. The 16-bit ADC Sense Resistor Gain value in
EE 0x68–0x69 scales Current() to mA. Adjusting ADC Sense Resistor Gain from its nominal value provides a
method to calibrate the current readings for system errors and the sense resistor value (RS). The nominal value
is set by
