(1) The wake-up time is measured from the edge of an external wake-up signal (for example, port interrupt or wake-up event) to the first
externally observable MCLK clock edge. MCLK is sourced by the DCO and the MCLK divider is set to divide-by-1 (DIVMx = 000b,
f_MCLK = f_DCO). This time includes the activation of the FRAM during wake up.
(2) The wake-up time is measured from the edge of an external wake-up signal (for example, port interrupt or wake-up event) until the first
instruction of the user program is executed.

(1) Charge used during the wake-up time from a given low-power mode to active mode. This does not include the energy required in active
mode (for example, for an interrupt service routine).
(2) Charge required until start of user code. This does not include the energy required to reconfigure the device.
