Hi,
this is about Chip's interpreter, discussed here: https://forums.parallax.com/discussion/171196/pnut-spin2-latest-version-v55-improved-bytecode-efficiency-for-reading-writing-bitfields/p77
and found here: https://github.com/parallaxinc/P2_PNut_Public/blob/master/Spin2_interpreter.spin2

I am trying to get some understanding, how this works.

There is some "trap_flag" mentioned. Can someone enlighten me, what that means or is?

Thank you!
Christof
