1. The analog supply current is the sum of the active or disabled current for each of the analog modules on the device. See
each module's specification for its supply current.
2. 50MHz core and system clock, 25MHz bus clock, and 25MHz flash clock . MCG configured for FEI mode. All peripheral
clocks disabled.
3. 50MHz core and system clock, 25MHz bus clock, and 25MHz flash clock. MCG configured for FEI mode. All peripheral
clocks enabled, and peripherals are in active operation.
4. Max values are measured with CPU executing DSP instructions
5. 25MHz core and system clock, 25MHz bus clock, and 12.5MHz flash clock. MCG configured for FEI mode.
6. 4 MHz core, system, and bus clock and 1MHz flash clock. MCG configured for BLPE mode. All peripheral clocks disabled.
Code executing from flash.
7. 4 MHz core, system, and bus clock and 1MHz flash clock. MCG configured for BLPE mode. All peripheral clocks enabled
but peripherals are not in active operation. Code executing from flash.
8. 4 MHz core, system, and bus clock and 1MHz flash clock. MCG configured for BLPE mode. All peripheral clocks disabled.
9. Includes 32kHz oscillator current and RTC operation.
