Note 44: Current sunk by the pin if the external voltage is higher than one the circuit tries to force.
Note 45: The threshold is equal to actual VRefO.
Note 46: In the regions of VCC where the device's operation is disabled, the H-drive, V-drive and B+-drive signals on
HOut, VOut and BOut pins, resp., are inhibited, the I2C Bus does not accept any data and the XRayAlarm flag
is reset. Also see Figure 16
Note 47: See Figure 10
