Figure 32-10. Idle Supply Current vs. VCC (Internal RC Oscillator, 128kHz)I

32.2.1

Supply Current of IO modules

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 Reduc-

tion Register. See “Power Reduction Register” on page 52 for details.
