Hello,
I have a little issue with "bitc".
If I use "P1OUT&= ~0x08;" I got "bic.b #8,&0x0021"
but if I use "P1OUT&= ~0x80;" I got
mov.b #127, r15
and.b r15,&0x0021
with "P1OUT&= (uint8_t)~0x80; I got
and.b #127,&0x0021
P1OUT&= ~0x40 --> and.b #-65,&0x0021
which is better but not the expected result.
It looks like it depends on the value( high nibble doesn't work).
- why is it
- how I can get the bic (not using inline assembler)
Any ideas?
You didn't say what -Ox you where using. But if -O0, I would expect the
compiler to take the longest route possible. Longer than anyone doing
assembly would think. But this works great for debugging.
Is that the case?
Best, Dan.
