are controlled by the Power Reduction Register. See
details.

It is possible to calculate the typical current consumption based on the numbers from
for other V
Calculate the expected current consumption in idle mode with USART0, TIMER1, and SPI
enabled at V
add 13.1% for the USART0, 13.0% for the SPI, and 13.2% for the TIMER1 module. Reading
from
F = 1MHz. The total current consumption in idle mode with USART0, TIMER1, and SPI enabled,
gives:
