9.3 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 SYSAHBCLKCFG
and PDRUNCFG (for analog blocks) registers. All other blocks are disabled in both
registers and no code is executed. Measured on a typical sample at T
noted otherwise, the system oscillator and PLL are running in both measurements.
The supply currents are shown for system clock frequencies of 12 MHz and 48 MHz.

Notes
System oscillator running; PLL off; independent
of main clock frequency.
IRC running; PLL off; independent of main clock
frequency.
System oscillator running; PLL off; independent
of main clock frequency.
Independent of main clock frequency.
Main clock divided by 4 in the CLKOUTDIV
register.
GPIO pins configured as outputs and set to
LOW. Direction and pin state are maintained if
the GPIO is disabled in the SYSAHBCLKCFG
register.
Main clock selected as clock source for the
WDT.
