Consider some AVR clocked from low-power crystal at 1 MHz and prescaler set to 1:32. What will be power consumption in Idle mode (with all peripherals turned off, as in datasheet)? Obviously not less than in Standby mode at 1 MHz, and not less than in idle mode @ 32 KHz, but how much will high-frequency part before prescaler will contribute to the total consumption compared to standby mode?
