What's the use of "&=" and "|=" operators when used for microprocessors programming?

These statements are equivalent:
x = x & 0x01;
x &= 0x01;
It means to perform a bitwise operation with the values on the left and right-hand side, and then assign the result to the variable on the left, so a bit of a short form. If you're not familiar with bitwise operations, I suggest you start getting familiar with those first - the
& being a bitwise AND and the
| being a bitwise OR.
Hope that helps!
