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! 5.4 Pinouts for P6980 Tek Probe Names Hypertransport Support Names Land Sig Head #C10 Land Sig Head #C10 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 A13 A14 A15 A16 A17 A18 A19 A20 A21 A22 A23 A24 A25 A26 A27 D0+ D0GND D2+ D2GND D4+ D4GND D6+ D6GND NC NC GND D8+ D8GND D10+ D10GND D12+ D12GND D14+ D14GND Unused Unused GND Unused Unused GND Unused Unused GND Unused Unused GND NC NC GND D8+ D8GND D10+ D10GND D12+ D12GND D14+ D14GND B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 B11 B12 B13 B14 B15 B16 B17 B18 B19 B20 B21 B22 B23 B24 B25 B26 B27 GND D1D1+ GND D3D3+ GND D5D5+ GND D7D7+ GND C/QC/Q+ GND D9D9+ GND D11D11+ GND D13D13+ GND D15D15+ Page 21 of 23 GND Unused Unused GND Unused Unused GND Unused Unused GND Unused Unused GND HighByteClkHighByteClk+ GND D9D9+ GND D11D11+ GND D13D13+ GND D15D15+
