Table 8. Power consumption for individual analog and digital blocks
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 SYSAHBCLKCTRL or 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

C. Unless noted otherwise,
the system oscillator and PLL are running in both measurements.
