Rotating 32-bit binary data to the right
DROR(P), DRCR(P)
• DROR(P): These instructions rotate the 32-bit binary data to the right by (n) bit(s), excluding the carry flag.
• DRCR(P): These instructions rotate the 32-bit binary data to the right by (n) bit(s), including the carry flag.
*1 The DROR instruction does not support the ST and FBD/LD. Use the standard function, ROR.
