7 - ELECTRICAL PARAMETERS AND OPERATING CONDITIONS
The 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". The 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.
TH is the period of horizontal deflection.
