Flag
CY
1 if the bit shifted out last is 1; otherwise, 0.
However, if the number of shifts is 0, the result is 0.
0
1 if the result of an operation is negative; otherwise, 0.
1 if the result of an operation is 0; otherwise, 0.

Instruction
(1) SHL Shift Logical Left by Register
(2) SHL Shift Logical Left by Immediate (5-bit)
Explanation
(1) Logically shifts the word data of general register reg2 to the left by ‘n’ positions, where ‘n’
is a value from 0 to +31, specified by the lower 5 bits of general register reg1 (0 is shifted
to the LSB side), and then writes the result to general register reg2. If the number of shifts
is 0, general register reg2 retains the same value prior to instruction execution. The data
of general register reg1 is not affected.
(2) Logically shifts the word data of general register reg2 to the left by ‘n’ positions, where ‘n’
is a value from 0 to +31, specified by the 5-bit immediate data, zero-extended to word length
(0 is shifted to the LSB side), and then writes the result to general register reg2. If the
number of shifts is 0, general register reg2 retains the value prior to instruction execution.
