Note 39: Current sunk by the pin if the external voltage is higher than one the circuit tries to force.
Note 40: The threshold is equal to actual VRefO.
Note
41:
In the
HOut,
regions of
VOut and
VCC where
BOut pins,
the device’s operation is disabled, the
resp., are inhibited, the I2C Bus does
H-drive, V-drive and B+-drive signals on
not accept any data and the XRayAlarm
flag is reset. Also see Figure 15
