Description

Rotates to the right with the C flag 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.

Bit 0 moves to the C flag, bits 1 through 7 move to the next lowest-order bit position, and the C flag moves to bit 7. See Figure 12 for an illustration.
