INT - Interrupt

	Usage:	INT	num
	Modifies flags: TF IF

	Initiates a software interrupt by pushing the flags, clearing the
	Trap and Interrupt Flags, pushing CS followed by IP and loading
	CS:IP with the value found in the interrupt vector table.  Execution
	then begins at the location addressed by the new CS:IP
