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 Reduction Register. See “When the SM2:0 bits are 111 and an
external crystal/resonator clock option is selected, the SLEEP instruction makes the MCU enter
Extended Standby mode. This mode is identical to Power-save mode with the exception that the
