Power Consumption Device Only 50MHz REF_CLK OUT Mode
Power measurements taken over the operating conditions specified. See
of the power down modes. For more information on 50MHz REF_CLK OUT mode, see
Table 7.5 Power Consumption Device Only (50MHz REF_CLK OUT MODE)
VDD2A, or from an external 1.2V supply when the internal regulator is disabled.
Table 7.4 Power Consumption Device Only (REF_CLK IN MODE)
This is calculated with full flexPWR features activated: VDDIO = 1.8V and internal regulator
disabled.
Current measurements do not include power applied to the magnetics or the optional
external LEDs.
