/* Note:
   The -A and -B versions include a CPU Detection Reset Circuit. 
   This must be cleared periodically to prevent program reset.

   The conditions for clearing the counter of this circuit are given below:
   1. Writing 0 to CL bit of LVRC register
   2. Internal reset
   3. Stopping main oscillation clock
   4. Transition to sleep mode
   5. Transition to time-base timer mode or timer mode
   6. Starting hold
