unsigned char dest;
dest |= ( 1 << ( src & 7 ));
(2)When dest is a register:
register unsigned long dest;
dest |= ( 1 << ( src & 31 ));
[Function]
- | This instruction sets the bit of dest, which is specified by src. |
- | The immediate value given as src is the number (position) of the bit. |
- | The range for IMM:3 operands is 0 ? IMM:3 ? 7. The range for IMM:5 is 0 ? IMM:5 ? 31. |
