Integer Instructions
ROL, ROR
Operation:
Assembler
Syntax:
Attributes:
Description: Rotates the bits of the operand in the direction specified (L or R). The extend
4-160
bit is not included in the rotation. The rotate count for the rotation of a register is
specified in either of two ways:
The size of the operation for register destinations is specified as byte, word, or long.
The contents of memory, (ROd < ea > ), can be rotated one bit only, and operand size
is restricted to a word.
The ROL instruction rotates the bits of the operand to the left; the rotate count deter-
mines the number of bit positions rotated. Bits rotated out of the high-order bit go to the
carry bit and also back into the low-order bit.
The ROR instruction rotates the bits of the operand to the right; the rotate count deter-
mines the number of bit positions rotated. Bits rotated out of the low-order bit go to the
carry bit and also back into the high-order bit.
1. Immediate—The rotate count (1 – 8) is specified in the instruction.
2. Register—The rotate count is the value in the data register specified in the in-
struction, modulo 64.
