  Hi Dave,
  I'm using your Lab Manual for the Intro to Mixed Signal... book. I hit a snag and wonder if you can spend a moment and tell me how I've messed up.
  I'm doing Lab1B... changed to pull-up in the port 1 bits and went back to 12 MHz for the CPU_CLK.
  When shorting bit0 and bit6, I predicted a comb waveform where the bit6 low state had the wire ANDed output low and where the bit6 high state had the bit0 waveform.
  Indtead, I get a steady state 1v level (appx).
  
  I am using the 27443 and tried both the cy3210psocEVAL1 and the cy3210-miniEVAL1 boards.
  Psoc Designer 5.0 and Psoc Programmer 3.0.0.92. I tried this with two different 27443's.
  
  Thanks
  Tim Miner
