Power-Down Supply Current
Atmel ATmega16/32/64/M1/C1
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 con-
trolled by the Power Reduction Register. See
details.
