Electrical characteristics
3.9
The power consumption of an I/O segment depends on the usage of the pins on a particular segment. The power consumption
is the sum of all output pin currents for a particular segment. The output pin current can be calculated from
the voltage, frequency, and load on the pin. Use linear scaling to calculate pin currents for voltage, frequency, and load
parameters that fall outside the values given in
