The RTC registers that store second, minute, hour, day-of week, operating mode, and A.M./P.M.
data are not reset by an STBY input. Therefore, all registers must be set to their initial values after
power-on and STBY input. Figure 11.3 shows the initial setting and resetting procedures of the
RTC. Once the register setting are made, the RTC provides an accurate time as long as power is
supplied regardless of a RES input.
