INTERRUPT OPERATION
Alarm Interrupt
When AIE is 1 and an alarm event occurs (AF bit is set to 1), AIRQN output goes LOW. If AIE is 0, however,
AIRQN is in a high-impedance state. The alarm interrupt is output when a carry from the seconds register to
the minute register occurs.
Timer Interrupt
The timer interrupt mode (level interrupt or periodic interrupt) is selected by the setting of TI/TP.
Level interrupt mode (TI/TP = 0)
When TIE is 1 and a timer interrupt event occurs (TF bit is set to 1), TIRQN goes LOW. When TIE is 0, how-
ever, TIRQN is in a high-impedance state.
