Unconditional jump to symbolic address
Conditional jump to symbolic address
(If the RLO = ”0”, it is set to ”1”)
Jump if the result is zero: the jump is only made if
CC1 = 0 and CC0 = 0. The RLO is not changed.
Jump if the result is not zero: the jump is only made if
CC1 CC0. The RLO is not changed.
Jump if the result is less than zero: the jump is only made if
CC1 = 0 and CC0 = 1. The RLO is not changed.
Jump on overflow: the jump is only made if the OVERFLOW bit
is set. The RLO is not changed.
Jump if the result is greater than zero: the jump is only made if
CC1 = 1 and CC0 = 1. The RLO is not changed.
Shift the contents of ACCUM 1 to the right by the value
specified in the parameter.
Positions becoming vacant are padded with zeros.
CC1/CC0 are affected
Shift the contents of ACCUM 1 to the left by the value specified
in the parameter.
Positions becoming vacant are padded with zeros.
CC1/CC0 are affected
Shift Operations
Form the two's complement of ACCUM 1.
CC1/CC2 and OV are affected
Form the one's complement of ACCUM 1.
