32-bit ARM Cortex-M3 microcontroller
10.2 Peripheral power consumption
The supply current per peripheral is measured as the difference in supply current between
the peripheral block enabled and the peripheral block disabled in the PCONP register. All
other blocks are disabled and no code is executed. Measured on a typical sample at
Tamb = 25 °C. The peripheral clock PCLK = CCLK/4.
