Micro Second Bus Interfaces (MSC0, MSC1)
The Micro Second Channel (MSC) interfaces provides a serial communication link
typically used to connect power switches or other peripheral devices. The serial
communication link is build up by a fast synchronous downstream channel and a slow
asynchronous upstream channel. Figure 10 shows a global view the interface signals of
the MSC interface.
