[~] [,
next A
]
MOVS MR, A
n
[~]
Transfer accumulator (A~=0) or offset accumulator (A~=1)
to MR register in the signed multiplier mode (UM bit in
status register set to 0). Transfer status is modified.
1 0 1 1 1 MOVU MR, A
n
[~] [,

n
[~]
Multiply the MR register by accumulator (A~=1) or offset
accumulator (A~=0) , subtract lower 16 bits of the product
from the offset accumulator (A~=1) or accumulator
(A~=0). Store in the accumulator (~A=0) or offset
accumulator (~A=1). Latch the upper 16 bits in PH. ALU
status is modified.

[~]
Multiply MR register by accumulator (A~=1) or offset
accumulator (A~=0) , add lower 16 bits of product to offset
accumulator (A~=1) or accumulator (A~=0) and store to
accumulator (~A=0) or offset accumulator (~A=1). Latch
upper 16 bits in PH. ALU status is modified.

(A~=0) value n bits left (SV reg). Store the upper 16 bits to
PH. Subtract the lower 16 bits of value from offset (A~=1)
or accumulator (A~=0) and store in accumulator (~A=0) or
offset accumulator (~A=1). ALU status is modified.

Barrel shift the accumulator(A~=1) or offset accumulator
(A~=0) value n bits left (SV reg). Store the upper 16 bits to
PH. Add the lower 16 bits of value to offset accumulator
(A~=1) or accumulator (A~=0) and store in accumulator
(~A=0) or offset accumulator(~A=1). ALU status is
modified.
