4.6.5 I/O pad current specification
The I/O pads are distributed across the I/O supply segment. Each I/O supply is associated to a VDD/VSS_HV supply pair as
described in Table 19.
Table 20 provides I/O consumption figures.
In order to ensure device reliability, the average current of the I/O on a single segment should remain below the IAVGSEG
maximum value.
In order to ensure device functionality, the sum of the dynamic and static current of the I/O on a single segment should remain
below the IDYNSEG maximum value.
