When the Sigma is configured in one of the modes, all the program steps of the lower-
priority modes are ignored.
The “astronomical” and “periodic” modes, which are accessible only via software
programming on a PC, do not have high priority (the astronomical, periodic and
weekly modes, which will rarely be programmed together on the same circuit, are
lumped together at low level).
