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
Idle mode. The enabling or disabling of the I/O modules are controlled by the power reduction register. See Section 6.6
“Power Reduction Register” on page 36 for details.
