The RTC utilizes two prescaler blocks (RT0PS, RT1PS) to generate a 128Hz and 1Hz clock, respectively, from the source 32.768kHz RTCCLK. The prescaler blocks each support generating a periodic interrupt alarm at a variety of rates from 4096Hz down to 0.5Hz. The 1Hz clock output from RT1PS ticks the counter block, which tracks seconds, minutes, hours, and day of the week. The counter block also sources an interval alarm interrupt once per minute, per hour, at midnight, or at noon. The counter midnight output sources the calendar block, which provides day of the month, month, and year, with leap year correction. Two independent calendar alarm interrupts are provided to wake the application at specific times.
