INT Interrupt Status. When this bit is high a Tick Timer 2
interrupt is being generated at the level programmed in

cleared by writing a logic 1 into the ICLR control bit.
Tick Timer 1 Interrupt Control Register
IL2-IL0 Interrupt Request Level. These three bits select the
interrupt level for Tick Timer 1. Level 0 does not generate
an interrupt.
