It's mainly useful for setting up registers in advance; the parallel moves often get bottlenecked by the data bus anyway. > b) serial ports (2 for the C30, 1 for the C31) The 56k has 2 serial ports and a parallel port. It can generate baud rates internally. Actually, I think the interfacing capabilities are one of its strong points. The Motorola documentation of those capabilities is not one of its strong points.
