+          The Tegra210 timer provides fourteen 29-bit timer counters and one 32-bit
+          timestamp counter. The TMRs run at either a fixed 1 MHz clock rate derived
+          from the oscillator clock (TMR0-TMR9) or directly at the oscillator clock
+          (TMR10-TMR13). Each TMR can be programmed to generate one-shot, periodic,
+          or watchdog interrupts.
