Description
Rotates to the left with the C flag the contents of r (any of the register A, B, C, D, E, H, or L). Each bit in the
register moves to the next highest-order bit position (bit 0 moves to bit 1, etc.) while the C flag moves to bit 0
and bit 7 moves to the C flag. See Figure 1 on page 115.
