ComPorts

These communication links follow Texas Instrument C4x standard. They are 8-bit
parallel inter-processor ports of the 'C4x processors.
The 398 follows the C40 TIM standard and as such provides 6 links. These are given
the numbers 0, 1, 2, 3, 4 and 5. The following figure shows how the 2 configuration
ComPorts (FPGA ) are connected on the TIM.
They are guaranteed for a transfer rate of 20MB/s, which could lead, using the
6 ComPorts available to a 120MB/s transfer rate.
The ComPort drives at 3.3v signal levels.
