Note 3-11
The basic timers in this device have an auto-reload mode. When this mode is selected, the block's
clk_req equation is always asserted, which will prevent the device from gating its clock tree and going
to sleep. When the firmware intends to put the device to sleep, none of the timers should be in auto-
reload mode. Alternatively, use the timer's HALT function inside the control register to stop the timer
in auto-reload mode so it can go to sleep.
