9.3.3 Example of a Circular Rotate Bits Left On Transition Instruction
When switch1 transitions from false to
true, the two most significant bits (bits
15 and 14) of the integer variable
diagnostic are shifted out, the
remaining bits are shifted left, and the
former most significant bits (bits 15
and 14) are placed into bits 1 and 0.
The state of the variable status reflects
the value in bit 0. In this case, the
variable status is false.
