Well, this is not true. You use in yourd board a lot of these constants.
There are only a few of them that are not used and

You can drop this line

Values are defined in Table 47 in MC13892.h manual. The low level is 0.6
Volt, that corresponds to "0x0", and each bit increments the voltage by
25mV. I can suggest to add a macro to mc13892.h that return the value
for register when the desired voltage (in millivolt) is passed.

..and use it here, too.

..and here.

I have not checked before, but this is not the coding style for
multiline comments.
