I just want to confirm that on production board using the HCS08QG8 device that no external pullup resistors are required for the BMD header.  This application will use the P&E USB BDM Mulitlink tool to program the part.  The P&E tool has open drain outputs and the QG8 has pullup resistors for the RESET and BKGD\MS pins.  Knowing this, external pullup resistors are not required to program the part using the BDM?
