If this condition were to occur, the Parallel Load Mode's Verify cycle would be invoked. As a result, serial communication between the KIT.EXE program on the PC and the serialloader on the DS5000 would not function. This is due to the fact that since RST and PSEN are being pulled high and low respectively to invoke the DS5000's Serial Load Mode operation, the addition ofP2.7 and P2.6 being pulled low would satisfy the condition for a Verify cycle on the device. The easiest way to insure that this does not occur is to assign either P2.7 0r P2.6 as an output from the target system. This will insure that at least one of these pins will be pulled high by its internal pull-up while the Serial Load Mode is in effect, as all port pins are set to a l (reset) state during this time.
