LD0.MDSOPT1 Generic operation time supervision
Since the register size is 16 bits, the value saturates at 65535 hours (approximately
7.5 years). Alternatively, a 32-bit user-definable register can be made of this data to
cover the whole 300 000 hours (34 years) range. The value can also, for example,
be rescaled to show “total operation days” instead by changing the scale factor
from 1 to 1/24 = 0.0417.
