Note: The letter h is used for hexadecimal values.
Transition from 0 to FFh is not a timeout condition.
Caution: Using the same instructions for stopping the counter/timers and setting
the status bits is not recommended.
Two successive commands are necessary. First, the counter/timers must be
stopped. Second, the status bits must be reset. These commands are required
because it takes one counter/timer clock interval for the initiated event to actually
occur. See Figure 22 and Figure 23.
