Supply Current of I/O modules

The table below can be used to calculate the additional current consumption for the different

I/O modules Idle mode. The enabling or disabling of the I/O modules are controlled by the

Power Reduction Register. See Section 5.9.3 “PRR – Power Reduction Register” on page 51

for details.
