Purely as an exploration(atm) i wondered what range of operations could be performed on the system through an interrupt without using x,y or a register.
For example i know we can check the interrupt that occurs using BIT followed by a branch (neither affecting registers).
We can also reset the IRQ with CMP or BIT.
One example is generating a triangle wave on Port A..
Code: Select all
skip1 ASL DirFlag
Or something like this?
