ADDV – Add Long Immediate Value or Data Memory Loca-
tion
Syntax:
addv ##long immediate, operand
Operation:
operand + ##long immediate
> operand
The operand and the long immediate values are sign-extended. If the
operand is not part of an accumulator (aXl, aXh, aXe, bXl, bXh), then
the accumulators are unaffected. If the operand is a part of an accumu-
lator, only the addressed part is affected.
Operand:
REG
(rN)
direct address
Affected Flags:
Z, M, C are a result of the 16-bit operation. M is affected by bit 15.
When the operand is st0, st0 (including the flags) accepts the addition
result regardless of a0e bits.
Cycles:
2
Words:
2
Notes:
The REG cannot be aX, bX, p, pc. Note that aX can be used in
add
##long immediate, aX instruction.
When adding a long immediate value to st0, st0 (including the flags)
accepts the ALU output result. When adding a long immediate value to
st1, the flags are affected by the ALU output, as usual.
Note that when the operand is part of an accumulator, only the
addressed part is affected. For example, if the instruction
addv ##long
immediate, a01 generates a carry. The carry flag is set. However, a0h is
unchanged. On the other hand, the instruction
addl ##long immediate,
a0l (with same a0 and immediate values) changes the a0h and affects
the carry flag according to bit 36 of the ALU result.
