7.1 Rotation Instruction
Rotating 16-bit data to the right
ROR(P), RCR(P)
• ROR(P): These instructions rotate the 16-bit binary data in the device specified by (d) to the right by (n) bit(s) (not including
the carry flag).
• RCR(P): These instructions rotate the 16-bit binary data in the device specified by (d) to the right by (n) bit(s) (including the
carry flag).
