Table 32-2.
It is possible to calculate the typical current consumption based on the numbers from
on page 390
Calculate the expected current consumption in idle mode with USART0, TIMER1, and TWI
enabled at V
add 17% for the USART0, 24% for the TWI, and 10% for the TIMER1 module. Reading from
ure 32-6 on page
