  I'm working on a 1080p digitizer app...
  Right now can display data on P63 via P60, triggered when it goes low.
  A lot of work still to do, but this could be useful for things like SPI, etc...
  
  For some reason, Graphics.spin is limited to x values less that 512. Not sure why, but need to fix that...
  
  Anyway, right now, you can hit a key in Propeller Serial Terminal and see the data waveform in this app

  If you look at inb[63] you can't see the actual data because it's in smartpin mode...

  That's why I like to make the distinction between pin modes and smartpin modes when talking about those WRPIN config bits. Only the M field is smartpin exclusive.

  Wasn't sure this would work or not... But it does!
  
  I just do a:

  wrpin   pinset,#60
  

  where:

                    ' %AAAA_BBBB_FFF_PPPPPPPPPPPPP_TT_MMMMM_0
  pinset      long    %0011_0000_000_0000000000000_00_00000_0

  I'm surprised that the smart pin is hiding the input data. I can't think of a reason to do that right now.
  
  I assume you mean inb[31]. But I could see some pin access methods that would ignore bit 5 and give the correct answer anyway.

  SaucySoliton,
  When a pin is in a smartpin mode, the IN for the pin is used to signal events related to the mode.

  When M != 0, IN and DIR stop doing their normal pin job and become special smartpin signals.
