We have used short hand where Dn by Hypertransport naming is really CADn.
Ctl +/- signals are clocked by the LowByteClk and should be routed accordingly.
LDTStop, LDTReq do not need to be provided for the Support to function.
Signals can be used non-differentially by attaching the signal to the + signal of the
diff pair and tying the negative signal to DC 600mV (HT midrail).
5) UsrN signals are provided for user use!
6) UsrN and LDTStop, LDTReq, Reset, and PwrOK are currently subsampled at
roughly 1/20 bus clock rate before being passed through to the logic analyzer.
However, fine time is maintained in the hardware so that other modes (not yet
defined) can be supported where the signals are used at full time resolution.
7) Note that in 8-bit systems, signals that are labeled “Timed to HighByteClk” will
not be available since there is no “HighByteClock” in an 8-bit system!
