LVDS signals are not routed to motherboard.
JTAG signals are not routed to motherboard.
EVT signals have the option of adding a jumper on
daughtercard to route signals to motherboard.
TDI, TDO, TCK, TMS & JCOMP are not connected to
daughter card.
PORST, ESR0, EVTI and EVTO are connected to daughtercard
Place CAPS as close to connector pins as
possible but do NOT fit cap C48 at board assembly.
