COGINIT execution time?
Does anybody know how much cycles it takes for a cog started with COGINIT in COGEXEC mode until it executes the first instruction? Of course, the COGINIT instruction itself only takes 2 cycles in the starter cog. But the target cog then has to load all of its cog RAM. I thought due to the clever "rotating" bus bars of the… -

inline pasm interrupt routine local variables

I thought that if I stayed in the method that it was created with, I could use the 15 local variables to communicate with the interrupt routine after the inline ends.
