1) The port groups are defined in Table 16.
Figure 7 shows the path of the input currents during overload via the ESD protection
structures. The diodes against V_DDP and ground are a simplified representation of these
ESD protection structures.

Table 14 and Table 15 list input voltages that can be reached under overload conditions.
Note that the absolute maximum input voltages as defined in the Absolute Maximum
Ratings must not be exceeded during overload.
