In real-time clock mode, a 1-second signal is generated from fC4 using a divide-by-2 frequency divider, 4-bit
counter, and 8-bit counter and used to count seconds, minutes, hours, and days of the week. Figure 21.1 shows
a Block Diagram of Real-Time Clock Mode, Table 21.2 lists the Real-Time Clock Mode Specifications, and
Table 21.3 lists Interrupt Sources. Figure 21.2 shows the Definition of Time Representation and Figure 21.3
shows an Operating Example in Real-Time Clock Mode.
