So what's stopping you? You're inside an asm. lang ISR, right? Do what you
need to
do.

Set/clear the bit, figure out where the register is on the stack, and change the
bit
there too, so when you exit the ISR you won't flip the bit back to what it was.

Hi All

I want to know if there is trick to toggle the XF pin inside an interrupt.
The XF bit is located inside status register 1 and this register is
pushed-poped on the stack inside the interrupt so I'm unable to change it
state.

Thanks
