27.6.4 Time Counter Group
Description
Seconds value in the range of 0 to 59
Minutes value in the range of 0 to 59
Hours value in the range of 0 to 23
Day of month value in the range of 1 to 28, 29, 30, or 31 (depending on the
month and whether it is a leap year).
Day of week value in the range of 0 to 6
Day of year value in the range of 1 to 365 (366 for leap years)
Month value in the range of 1 to 12
Year value in the range of 0 to 4095
The time value consists of the eight counters shown in
counters can be read or written at the locations shown in
Table 517. Time Counter relationships and values
[1]
The RTC does a simple bit comparison to see if the two lowest order bits of the year
counter are zero. If true, then the RTC considers that year a leap year. The RTC considers
all years evenly divisible by 4 as leap years. This algorithm is accurate from the year 1901
through the year 2099, but fails for the year 2100, which is not a leap year. The only effect
of leap year on the RTC is to alter the length of the month of February for the month, day
of month, and year counters.
The following register is used to calibrate the time counter.

Description
Day of year value in the range of 1 to 365 (366 for leap years).
Reserved, user software should not write ones to reserved bits. The value read from a
reserved bit is not defined.
These values are simply incremented at the appropriate intervals and reset at the defined overflow point.
They are not calculated and must be correctly initialized in order to be meaningful.
