Typing error in code, What does it do?

I accidentally used a pling (!) character instead of a bar (|) in a piece of code

TCCR1A != (1 << WGM10);

The code compiled ok but correcting the error changed the program size by 4 bytes.

Is the pling used for bitwise operations or should the syntax checker have flagged an error?

The exclamation point is used in C as logical negation. != is "Not Equal".

If you compiled with appropriate warnings enabled this would have given you the warning 'filename:linenumber: warning: statement with no effect'

Normally you would use !=

if(a != b ) 
{ 
// Code inside here will only run if a is not equal to b
}
