Z80 has two different types of bit rotates. |
|||
* <code>RL/RR</code> rotates through the carry. The state of the carry before the rotate gets rotated in, and the bit that rotates out is put into the carry. |
|||
* <code>RLC/RRC</code> copies the bit "pushed out" to the carry but the old carry isn't rotated in. |
