The three time alarm bytes can be used in two ways. First, when the alarm time is written in the
appropriate hours, minutes, and seconds alarm locations, the alarm interrupt is initiated at the specified
time each day if the alarm enable bit is high. The second use condition is to insert a “don’t care” state in
one or more of the three time alarm bytes. The “don’t care” code is any hexadecimal value from C0 to
FF. The two most significant bits of each byte set the “don’t care” condition when at logic 1. An alarm is
generated each hour when the “don’t care” bits are set in the hours byte. Similarly, an alarm is generated
every minute with “don’t care” codes in the hours and minute alarm bytes. The “don’t care” codes in all
three time alarm bytes create an interrupt every second. The three time-alarm bytes can be used with the
date alarm as described in Wake-Up/Kickstart. The century counter is discussed later in this text.
