Note 35: Current sunk by the pin if the external voltage is higher than one the circuit tries to force.
Note 36: The threshold is equal to actual VRefO.
Note 37: 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.
