    RD (Reset port D specified by register Y)
    0000010100
    014
    11
    Grouping:
    Input/Output operation
    Description: Clears (0) to a bit of port D specified by register
    Y.
    Note:
    Set 0 to 3 to register Y because port D is
    four ports (D0–D3).
    When values except above are set to regis-
    ter Y, this instruction is equivalent to the
    NOP instruction.
    Operation:
    (D(Y))
    ← 0
    However,
    (Y) = 0 to 3

    Return operation
    Description: Returns from subroutine to the routine called
    the subroutine.
    Operation:
    (PC)
    ← (SK(SP))
    (SP)
    ← (SP) – 1

    Grouping:
    Return operation
    Description: Returns from interrupt service routine to
    main routine.
    Returns each value of data pointer (X, Y, Z),
    carry flag, skip status, NOP mode status by
    the continuous description of the LA/LXY in-
    struction, register A and register B to the
    states just before interrupt.

    Skip at uncondition
    Grouping:
    Return operation
    Description: Returns from subroutine to the routine called
    the subroutine, and skips the next instruction
    at uncondition.
    Operation:
    (PC)
    ← (SK(SP))
    (SP)
    ← (SP) – 1
    Operation:
    (PC)
    ← (SK(SP))
