Figure 141. Idle Supply Current vs. V
The tables and formulas below can be used to calculate the additional current consump-
tion 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 34 for details.
