Table D-2 shows all counter/timer modes of the RIO block and which functions can use
the given modes. The use of synch signals is allowed with all the functions, but does affect
the timer/counter so it may have an adverse affect on functions marked with * or #.
× — I/O are compatible with the given mode, and can work with any other function
using that mode.
* — I/O cannot share the block with any other * or # marked function without
possible conflicts.
# — I/O can generally share the timer, but will be affected by settings of the limit
value (value at which the timer rolls over) or resetting of the counter, either
directly or through synch signals.
