use by other applications and its value in no way affects the operating frequency of the global timers. The timers
operate at a ratio of this clock frequency, as set by TCR x [CLKR]. See

timers, the reload value is the contents of the corresponding GTBCR xn . Cascaded timers are reloaded with
either all ones, or the GTBCR xn contents, depending on the value of TCR n [ROVR]. See
