Description

Rotates to the right the data whose address is:

• 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.
