15 up-counter and can generate 4 interrupts when the counter reaches one of the
16 four preset counter values. The CPU local timers are 32-bit free running
17 down-counters and generate an interrupt when the counter expires. There is
18 one CPU local timer instantiated in MCT for every CPU in the system.
