Note 15. Depends on the system frequency and contents of DSP program.
Note 16. This is a reference value when using a crystal oscillator. Since most of the supply current at the initial reset state
is in the oscillator section, the value may vary according to the crystal type and the external circuit. This value is
just reference.
