Configuring a timer requires three basic steps:
1) If the timer is not currently in the hold state, place the timer in hold (HLD
= 0). Note that after device reset, the timer is already in the hold state.
2) Write the desired value to the timer period register.
3) Start the timer by setting the GO and HLD bits of the timer control register
to 1 and simultaneously writing the desired values to the timer control
register.
