C syntax for MC9S08GT60

[Shankman]

Hi,

I just wanted to know if anyone could explain this C syntax to me?

LED4 ^=1;

Thanks in advance

It can also be written as

LED4 = LED4 ^ 1;

which means

LED4 = LED4 XOR 1

which again means that if LED4 was 0 it will become 1 and if it was 1 it will become 0.

There are quite a few good C guides out there on the web that I have found quite useful for quick reference, especially when able to search text quickly in web browsers. One that I use:
