Here's a snippet of C code that will set bit 10 within a 16 bit value:

Code:

value |= (1 << 10);

If the value is accessed by multiple threads then it might be a good idea to do it this way to ensure an atomic operation is performed:

Code:

DisableInterrupts();
value |= (1 << 10);
EnableInterrupts();
