serial interface (SI) piggybacks (RS232, RS485, Ethernet). The SCC1 channel of the
MC68(EN)360 provides the interface to the serial interface (SI) piggyback installed on
the VSBC-32(E). All other channels of the controller (SCC2, SCC3 and SCC4) are
ported to the CXC interface except for the SI-PB232 piggyback which has on-board
additional control provided by the SCC4 channel through the piggyback interface for
serial interface piggybacks.
Thanks to the fact that three out of four SCC channels are routed to the CXC interface
connector, also an CXM-SIO3 external serial interface module can be installed in the
system, which therefore becomes a sort of “privileged” serial I/O extension of the VSBC-
32(E) board itself. In addition to two non-optoisolated RS232 serial interface connectors
the external serial interface module supports again a serial interface piggyback and up
to three serial communications piggybacks with the relating interfacing options. Maxi-
mum one CXM-SIO3 module can be controlled by an VSBC-32(E) board.

Note...
The serial channel SCC4 is routed to both the piggyback inter-
face for serial interface piggybacks and the CXC and can be used
by either one or the other, not both at the same time.
