Processing details
• These instructions shift the (n1) bit(s) of data starting from the specified device to the left by (n2) bit(s).
Ex.
When (n1)=10 and (n2)=4
(d)+9 (d)+8
0 1
(SM700)
(d)+9 (d)+8
1
1
1
(1) Filled with 0s.
• Specify (n1) and (n2) so that the following condition is satisfied: (n1)>(n2). In the case of (n1)(n2), data is shifted by the
value of the remainder of (n2)(n1). However, if the remainder value is 0, no processing is performed.
• Specify (n1) within the range of 1 to 64.
• The (n2) bit(s) from the least significant bit is/are filled with 0(s). In the case of (n1)<(n2), the bits are filled with 0s by the
value of the remainder of (n2)(n1).
• If (n1) or (n2) is 0, no processing is performed.
