INT 70 C - IRQ8 - CMOS(Complementary Metal-Oxide-Semiconductor) A type of integrated circuit design known for its low power consumption. REAL-TIME CLOCK
Desc:	this interrupt is called when the real-time clock chip generates an
	  alarm or periodic interrupt, among others (see CMOS(Complementary Metal-Oxide-Semiconductor) A type of integrated circuit design known for its low power consumption. 0Bh).  The
	  periodic interrupt by default occurs 1024 times per second.
Notes:	many BIOSes turn off the periodic interrupt in the INT 70h handler
	  unless in an event wait (see INT 15/AH=83h,INT 15/AH=86h).
	may be masked by setting bit 0 on I/O port A1h
