b) Output span voltage adjustment (EEPROM name：SC)
The span voltage is adjusted.
The magnification factor in this table represents an adjustment factor benchmarked to a VOUT output of
4800mV (@VDD: 5V) as 1 (factor) = 100[%]/100[%].
The output and sensitivity describes the adjustable output voltages with the assumed reference
output (2400mV@VDD: 3V, 4800mV@VDD: 5V) when ESC[7:0] = 0 dec.
