Wake Up Timer Current Mantissa (M) Value*.
Wake Up Timer Current Mantissa (M) Value*.
Low-Duty Cycle Mode Duration (LDC)*.
If enabled, the LDC will start together when the WUT is supposed to start, and
the duration of the LDC is specified by the address 19h and the equation that
goes with it. In order for the LDC to work, the LDC value has to be smaller than
the M value specified in registers 15h and 16h.
LDC = 0 is not allowed here. Write at least decimal 1.
