ROR
Operation
n = RS or IMM4
Rotates the bits in register RD n positions to the right. The upper n bits of the register RD are filled with
the lower n bits. Two source forms are available. In the first form, the parameter n is contained in the
instruction code as an immediate operand. In the second form, the parameter is contained in the lower bits
of the source register RS[3:0]. All other bits in RS are ignored. If n is zero no shift will take place and the
register RD will be unaffected; however, the condition code flags will be updated.
