Explanation
1. This instruction divides the bits in the device specified by D into groups (n bits in a group), and then rotates these
groups to the left.
2. Only the DROL instruction can use the 32-bit counter, but not the device E.
3. For 16-bit instructions, the value of n must be between 1–16. For 32-bit instructions, the value of n must be
between 1–32. When n is less than 0, the instruction is not executed. When n exceeds the range, the instruction is
executed with n at the maximum value (32) of the range.
4. In general, the ROLP and DROLP pulse instructions are used.
