I may have asked this question some time ago> i tried to check did not find anything so here it goes. How to evaluate this operation:
PCA0MD &= ~0x40; PCA0MD is a register for a processor.
I think the &= is a bitwise And and the ~ is a bitwise not ? ...this would be performed on the 0x40 of the operators from left to right?

0x40 is a number with only the 7th bit set like ...0100 0000. The bitwise NOT flips all bits to ... 1011 1111. The bitwise AND removes the 7th bit from PCA0MD like it is set to 0 if it has been 1, or leaves it 0 if it has been 0 before.
Yeah, you asked already.
PCA0MD &= ~0x40; Need some help cyphering
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
