Select this to get a clocksource based on the Atmel Periodic Interval Timer. It has a relatively low resolution and the TC Block clocksource should be preferred.
Select this to get a high precision clocksource based on a TC block with a 5+ MHz base clock rate. On platforms with 16-bit counters, two timer channels are combined to make a single 32-bit timer. It can also be used as a clock event device supporting oneshot mode.
