In Figures C-6 and C-7, switch S6 uses the alternate configuration to
generate the VXIbus CLK10 signal. Instead of the onboard oscillator, the
VXI-1394 generates from the external CLK SMB connector and drives to
the backplane. You can choose whether to terminate the signal using S2.
Polarity remains irrelevant to these configurations.
