The timers above are labeled according to the clock they receive. The system timers are connected to the L4_SYS bus and clocked by the l4_sys_free_clk. The SP timers are connected to the L4_SP bus and clocked by l4_sp_clk.
SP timer 0 and SP timer 1 must be disabled before l4_sp_clk is changed to another frequency. You can then re-enable the timer once the clock frequency change takes effect.
