Sure thing! I'll jump on it when I get home.

Thanks!

The P1 has the odd quirk that instructions at address $1FF are cancelled.

Which doesn't mean that it can't be done :)

@konimaru So the behavior you described is verified. The following code was used:

CON
        _clkmode = xtal1 + pll16x
        _xinfreq = 5_000_000

PUB main
  cognew(@tester,0)

DAT
              org     0

tester  jmpret          $,      #setup

        or              dira,   Pin_CP          ' Set output pin
        or              outa,   Pin_CP          ' Drive pin high

        waitpeq         $,      #0

        hubop           vscl,   #%10000_000
setup   mov             vscl,   $-1
        jmp             #$1FF        

Pin_CP        long      |< 0

I copied the pin-driving lines directly from my 74HC165 driver, and used the logic analyzer test bench for the driver to verify:

Pin 0 is driven high, so the running indicator was reached.
