34.3.3 Supply Current of IO 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 Registersection for details.
