WARNING: due to a bug (whether in the debuggers or in the silicon, I don't
know), the freeze timers in debug mode cannot be set in program.
To be able to debug follow the procedure below:
If using PICKit3 or ICD3 as debugger, put a breakpoint on the "StartRTOS"
statement below and run the program.
Before continuing with the debugging, using the watch window set both T1CON
and T2CON to the value 0x0004000.
