  Cool, shows I've never used it.

  For any given X, a duty cycle of 50% produces the highest frequency output when using NCO_DUTY mode.

  Finally have spin code calling hubexec code working.
  
  It is really simple code that just flashes the P56 LED on the P2EVAL pcb. I had to cull my code back to only the basics to get something working.

  CON
    _clkfreq      = 297_000_000		                    'set clock frequency
    LED_p2eval    = 56                                    ' P2EVAL Blue LED 0=ON
  
  PUB go()
  
      repeat
  '        PINTOGGLE(LED_p2eval)
          PR0 := 10
          CALL(@_HubToggle)                               ' call Toggle LED
          WAITMS(4000)                                    ' 4s        
  
  
  DAT             
                orgh
  _hubToggle
  '              mov       PR0,#10                         ' spin pasm comms registers
  .loop         drvnot    #LED_p2eval                     ' flash P2EVAL blue led
                waitx     ##_clkfreq/2                    ' 0.5s
                djnz      PR0,#.loop
                RET                                       ' return
