I/O pad current specification

The I/O pads are distributed across the I/O supply segment. Each I/O supply segment is

associated to a VDD/VSS supply pair as described in Table 25.

Table 26 provides the weight of concurrent switching I/Os.

In order to ensure device functionality, the sum of the weight of concurrent switching I/Os on

a single segment should remain below 100%.
