2-3.Alarm time/Frequency duty setting register
There are two types of alarm time/frequency duty setting registers, sixteen-bit registers, which set alarm time or frequency
duty. They are switched by INTxAE or INTxFE register. AM/PM flag to be set must be in accordance with 12-hour or 24-hour
expression. If AM/PM flag is not rightly then set hour data is not met to alarm data. The alarm time/frequency duty setting
register is a write-only register.
(1) When INTxAE = 1
INT1 and INT2 registers are considered as alarm time data. Having the same configuration as the time and minutes registers
of real-time register configuration, they represent hours and minutes with BCD codes. When setting them, do not set any
none-existent day. Data to be set must be in accordance with 12-hour or 24-hour expression that is set at the status register.
(2) When INTxFE = 1
INT1 and INT2 registers are considered as frequency duty data. By turning each bit of the registers to "1", a frequency
corresponding to each bit is chosen in an ANDed form.
