Supply Current of IO Modules
Figure 30-102.Idle Supply Current vs. Vcc (Internal RC Oscillator, 8 MHz).
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
details.
