Function/Routine
Name
Description Input Output File Name
normalize()
puts a register into normal
form, in which the major
count of Wh is greater than
or equal to zero, and less
than 1,000,000,000. The
minor count of ce counts
(e.g. from w0sum) is made
to be less than 1 Wh and
positive, by transfering
larger amounts into the
major count.
uint8x_t *register_ptr none math.c
operating_lcd ()
Displays the number of
hours of operation.
void void rtc.c
OperatingHours()
Calculates hours of
operation from the last valid
mark.
none int32_t hours rtc.c
