Function
Form the one's complement of
ACCU 1.
Form the two's complement of
ACCU 1. CC 1 / CC 0 and
OV are affected.
Shift the contents of ACCU 1
to the left by the value
specified in the parameter.
Unassigned positions are
padded with zeros.
CC 1 / CC 0 are affected.
Shift the contents of ACCU 1
to the right by the value
specified in the parameter.
Unassigned positions are
padded with zeros.
CC 1 / CC 0 are affected.
Jump unconditionally to the
symbolic address.
Jump conditionally to the
symbolic address. (If the RLO
is "0", it is set to "1".)
Jump if the result is zero. The
jump is made only if CC 1=0
and CC 0=0. The RLO is not
changed.
Jump if the result is not zero.
The jump is made only if
CC 1 CC 0. The RLO is not
changed.
Jump if the result is greater
than 0. The jump is made only
if CC 1=1 and CC 0=0. The
RLO is not changed.
Jump if the result is less than 0.
The jump is made only if
CC 1=0 and CC 0=1. The
RLO is not changed.
Jump on overflow. The jump is
made only if the OVERFLOW
bit is set. The RLO is not
changed.
