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.

INSTRUCTION SET SUMMARY
ADD A,Meml ADD A←A + Meml
ADC A,Meml ADD with Carry A←A + Meml + C, C←Carry,
HC←Half Carry
SUBC A,Meml Subtract with Carry A←A − MemI + C, C←Carry,
HC←Half Carry
AND A,Meml Logical AND A←A and Meml
ANDSZ A,Imm Logical AND Immed., Skip if Zero Skip next if (A and Imm) = 0
OR A,Meml Logical OR A←A or Meml
XOR A,Meml Logical EXclusive OR A←A xor Meml
IFEQ MD,Imm IF EQual Compare MD and Imm, Do next if MD = Imm
IFEQ A,Meml IF EQual Compare A and Meml, Do next if A = Meml
IFNE A,Meml IF Not Equal Compare A and Meml, Do next if A ≠ Meml
