Table 29-17. Additional Current Consumption for the different I/O modules (absolute values)
Table 29-18. Additional Current Consumption (percentage) in Active and Idle mode
It is possible to calculate the typical current consumption based on the numbers from
18
Calculate the expected current consumption in idle mode with USART0, TIMER1, and SPI
enabled at V
to add 49.8% for the USART0, 48.6% for the SPI, and 46.3% for the TIMER1 module. Reading
from
F = 1MHz. The total current consumption in idle mode with USART0, TIMER1, and SPI enabled,
