88 Rabbit 2000/3000 Microprocessor
Description
Rotates to the right with the Carry Flag, CF, the data in word register DE or HL. Bit 0 moves to the CF, bits 1
through 15 move to the next lowest-order bit position, and the CF moves to bit 15. See Figure 3 on page 87.
These instructions were implemented for the Rabbit and are not available for the Z180.
Description
Rotates to the right with the Carry Flag, CF, the data in index register IX or IY. Bit 0 moves to the CF, bits 1
through 15 move to the next lowest-order bit position, and the CF moves to bit 15. See Figure 3 on page 87.
These instructions were implemented for the Rabbit and are not available for the Z180.
