Operands:
D: Device to be rotated
Explanations:
1. This instruction rotates the device content designated by D to the left for n bits.
2. This instruction adopts pulse execution instructions (ROLP).
Program Example:
When X0 goes from Off to On, the 16 bits (4 bits as a group) in D10 will rotate to the left, as shown in
