= 3.0V and F = 1MHz. The total current consumption in idle mode with USART, TIMER1, and
SPI enabled, gives:
ICCtotal ≈ 0.6mA • (1 + 0.156 + 0.085 + 0.053) ≈ 0.77mA

Example 3
All I/O modules should be enabled. Calculate the expected current consumption in active mode
at VCC = 3.6V and F = 10MHz. We find the active current consumption without the I/O modules
to be ~ 7.0mA (from Figure 27-2). Then, by using the numbers from Table 27-2 - second column,
we find the total current consumption:
CCtotal ≈ 7.0mA • (1 + 0.1 + 0.1 + 0.1 + 0.085 + 0.043 + 0.053 + 0.156 + 0.105) ≈ 12.2mA
