    The VIS instruction is a special case of the Indirect Transfer
    of Control addressing mode, where the double-byte vector
    associated with the interrupt is transferred from adjacent
    addresses in program memory into the Program Counter in
    order to jump to the associated interrupt service routine.
    14.4 INSTRUCTION TYPES
    The instruction set contains a wide variety of instructions.
    The available instructions are listed below, organized into
    related groups.
    Some instructions test a condition and skip the next instruc-
    tion if the condition is not true. Skipped instructions are
    executed as no-operation (NOP) instructions.
    14.4.1 Arithmetic Instructions
    The arithmetic instructions perform binary arithmetic such as
    addition and subtraction, with or without the Carry bit.
    Add (ADD)
    Add with Carry (ADC)
    Subtract (SUB)
    Subtract with Carry (SUBC)
    Increment (INC)
    Decrement (DEC)
    Decimal Correct (DCOR)
    Clear Accumulator (CLR)
    Set Carry (SC)
    Reset Carry (RC)
    14.4.2 Transfer-of-Control Instructions
    The transfer-of-control instructions change the usual se-
    quential program flow by altering the contents of the Pro-
    gram Counter. The Jump to Subroutine instructions save the
    Program Counter contents on the stack before jumping; the
    Return instructions pop the top of the stack back into the
    Program Counter.
    Jump Relative (JP)
    Jump Absolute (JMP)
    Jump Absolute Long (JMPL)
    Jump Indirect (JID)
    Jump to Subroutine (JSR)
    Jump to Subroutine Long (JSRL)
    Return from Subroutine (RET)
    Return from Subroutine and Skip (RETSK)
    Return from Interrupt (RETI)
    Software Trap Interrupt (INTR)
    Vector Interrupt Select (VIS)
    14.4.3 Load and Exchange Instructions
    The load and exchange instructions write byte values in
    registers or memory. The addressing mode determines the
    source of the data.
    Load (LD)
    Load Accumulator Indirect (LAID)
    Exchange (X)
    14.4.4 Logical Instructions
    The logical instructions perform the operations AND, OR,
    and XOR (Exclusive OR). Other logical operations can be
    performed by combining these basic operations. For ex-
    ample, complementing is accomplished by exclusiveORing
    the Accumulator with FF Hex.
    Logical AND (AND)
    Logical OR (OR)
    Exclusive OR (XOR)
    14.4.5 Accumulator Bit Manipulation Instructions
    The Accumulator bit manipulation instructions allow the user
    to shift the Accumulator bits and to swap its two nibbles.
    Rotate Right Through Carry (RRC)
    Rotate Left Through Carry (RLC)
    Swap Nibbles of Accumulator (SWAP)
    14.4.6 Stack Control Instructions
    Push Data onto Stack (PUSH)
    Pop Data off of Stack (POP)
    14.4.7 Memory Bit Manipulation Instructions
    The memory bit manipulation instructions allow the user to
    set and reset individual bits in memory.
    Set Bit (SBIT)
    Reset Bit (RBIT)
    Reset Pending Bit (RPND)
    14.4.8 Conditional Instructions
    The conditional instruction test a condition. If the condition is
    true, the next instruction is executed in the normal manner; if
    the condition is false, the next instruction is skipped.
    If Equal (IFEQ)
    If Not Equal (IFNE)
    If Greater Than (IFGT)
    If Carry (IFC)
    If Not Carry (IFNC)
    If Bit (IFBIT)
    If B Pointer Not Equal (IFBNE)
    And Skip if Zero (ANDSZ)
    Decrement Register and Skip if Zero (DRSZ)
    14.4.9 No-Operation Instruction
    The no-operation instruction does nothing, except to occupy
    space in the program memory and time in execution.
    No-Operation (NOP)
    Note:
    The VIS is a special case of the Indirect Transfer of Control addressing
    mode, where the double byte vector associated with the interrupt is
    transferred from adjacent addresses in the program memory into the
    program counter (PC) in order to jump to the associated interrupt
    service routine.
