6 ELECTRICAL PARAMETERS AND OPERATING CONDITIONS
Medium (middle) value of an I2C-bus control or adjustment register composed of bits D0, D1,...,Dn is the
one having Dn at "1" and all other bits at "0". Minimum value is the one with all bits at 0, maximum value
is the one with all at "1".
Currents flowing from the device (sourced) are signed negative. Currents flowing to the device are signed
positive.
