27.2.1 Using the Power Reduction Register
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. See “Power Reduction Register” on page 43 for
details.
