I see... for edge count and edge time, only individual timers and not 
concatenates. I've had a look to the LM3S9D96, and it is more or less 
the same (the exception is that it is marketed as 4 32-bit timers that 
can be used as 8 16-bit timers :) ), and I suspect that all the family 
will have similar behaviout. A pity... since for Ethernet it includes 
the LAN and PHY on-chip.

Javier
