Comm-ports on the SMT335E

An SMT335E TIM has access to six FIFO-buffered comm-ports, fully compliant with
the Texas Instruments' standard [3].
Each comm-port is associated with two 15x32-bit unidirectional FIFOs; one for input
and one for output. An additional one-word buffer makes them appear as 16x32-bit
FIFOs. These allow the guaranteed maximum transfer rate of 20MB/s to be achieved.
