Auxiliary Status/Control Packet
RCP8 contains 64 auxiliary status and control variables, labeled S[0:63]
and C[0:63].
These bits may be sent to and from the host computer in the form of 13-byte BITE packets holding the full set of 64 bits.
The format of these packets is the same in both directions, and the identification byte is selectable so that conflicts with other BITE packets can be avoided. A subset of the auxiliary bits may optionally be assigned to electrical input and output lines on an I/O-62 card using the softplane.conf file. The auxiliary can also be set and accessed with logic equations.
