The real time clock (RTC) is used to supply a regular internal interrupt. Its time-out period is 1000ms. If the RTC
time-out occurs, the interrupt request flag RTCF and the RTCTO flag will be set to 1. The interrupt vector for the RTC is
14H. When the interrupt subroutine is serviced, the interrupt request flag (RTCF) will be cleared to 0, but the flag
RTCTO remain in its original value. If the RTCTO flag is not cleared, next RTC time-out interrupt will occur.
