10.2 Peripheral power consumption
The typical power consumption at T = 25 C for each individual peripheral is measured as
follows:
1. Enable all branch clocks and measure the current I
DD(REG)(3V3)
.
2. Disable the branch clock to the peripheral to be measured and keep all other branch
clocks enabled.
3. Calculate the difference between measurement 1 and 2. The result is the peripheral
power consumption.
