34.3.3 Supply Current of I/O Modules
The tables and formulas below can be used to calculate the additional current consumption for the
different I/O modules in Active and Idle mode. The enabling or disabling of the I/O modules are controlled
by the Power Reduction Register (PRR). See the Power Reduction Register section for details.
