WebRotate Through Carry Right (RCR) In the rotate through carry right instruction, the carry flag is inserted from the left, every bit moves one position to the right, and the right most bit is dropped in the carry flag. Effectively this is a nine bit or a seventeen bit rotation instead of the eight or sixteen bit rotation as in the case of simple ... WebRCR (Rotate Through Carry Right) rotates bits in the byte, word, or doubleword destination operand right by one or by the number of bits specified in the count operand (an immediate value or the value contained in CL). This instruction differs from ROR in that it treats CF as a low-order one-bit extension of the destination operand. family wellness clinic \u0026 regenesis md

WebMar 6, 2024 · Rotate through carry is a variant of the rotate operation, where the bit that is shifted in (on either end) is the old value of the carry flag, and the bit that is shifted out (on the other end) becomes the new value of the carry flag.

The most significant bit is rotated to the carry flag, the carry flag is rotated to the least significant bit position, all other bits are shifted to the left. The result includes the original value of the carry flag. The first operand value indicates how many times the rotate takes place.
