This interrupt handler controls the periodic and alarm interrupt functions from
the RTC. The periodic function, when activated, occurs 1024 times per second.
The Dword counter is decremented by 976 at each interrupt. When the location
becomes equal to or less than zero, bit seven of the designated location is set.
The alarm function of the RTC provides an interrupt at the specified time and
software Interrupt 4Ah is issued.
