Description
Rotates to the right the data whose address is:
- HL, or
- the sum of IX and the 8-bit signed displacement d, or
- the sum of IY and the 8-bit signed displacement d.
Each bit moves to the next lowest-order bit position (bit 7 moves to bit 6, etc.) while bit 0 moves to both bit
7 and the C flag. See Figure 16 for an illustration.
