Arithmetic division
Invert; operand is logically complemented
Logical AND
Logical OR
Logical exclusive OR
Shift left (example: D0 << 3 is shift D0 left 3 bits)
Shift right (example: D0 >> 3 is shift D0 right 3 bits)
Source operand is moved to destination operand
Two operands are exchanged
All bits of the upper portion are made equal to the high-order bit of the lower portion
Test the condition. If true, the operations after then are performed. If the condition is false and the
optional else clause is present, the operations after else are performed. If the condition is false and
else is omitted, the instruction performs no operation. Refer to the Bcc instruction description as an
example.
