15.4.3
Figure 15.3 shows how to read the time.
If a carry occurs while reading the time, the correct time will not be obtained, so it must be read
again. Part (a) in figure 15.3 shows the method of reading the time without using interrupts; part
(b) in figure 15.3 shows the method using carry interrupts. To keep programming simple, method
(a) should normally be used.
