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.
