RSTPE cleared at power on = no debugger?

It appears that I've permanently disabled one of my development boards running Kinetis KE06Z with the Kinetis Design Studio toolset and P&E Micro Multilink Universal.


I wrote code this after to clear SIM_SOPT0 register, to free up the NMI pin for use as I/O; but writing zero to the register also disables the RESET pin! This code runs early at power on, and it appears to mean that the P&E debugger can no longer access the processor.


Does anyone know of a way to recover from this?
