The ReStructured Text used was not properly formatted, resulting in
confusing and broken output.  This corrects the output and lets it

     The Timer is implemented as a countdown timer that can be used in various modes:
-    - Polling : Returns current countdown value to software.
-    - One-Shot: Loads itself and stops when value reaches 0.
-    - Periodic: (Re-)Loads itself when value reaches 0.
 
-    `en` register allows the user to enable/disable the Timer. When the Timer is enabled, it is

     automatically loaded with the value of `load` register.
 
-    When the Timer reaches 0, it is automatically reloaded with value of `reload` register.

     To use the Timer in One-Shot mode, the user needs to:
-    - Disable the timer.
-    - Set the `load` register to the expected duration.
-    - (Re-)Enable the Timer.
